SuperATV is the largest single brand in our catalog, which means the hard part is not finding a SuperATV part for your machine. It is choosing between the three or four SuperATV parts that all fit. This guide covers the company, the sub-brands, the real specs behind each product line and the warranty terms that separate them.
SuperATV started with one lift kit. Founder Harold Hunt was a creek rider who wanted his machine to do things the factory setup would not do, and the first product came out of that gap between what riders wanted and what dealers stocked.
| Year | What happened |
|---|---|
| 2004 | Harold Hunt founds SuperATV in Madison, Indiana. First product is a lift kit. |
| 2004–2014 | Catalog expands from suspension into windshields, doors, axles, tires and machine protection. In-house manufacturing and testing become the core of the operation. |
| 2015 | The 4" GDP Portal Gear Lift launches, the first side-by-side portal kit to gain real market traction. Six-inch kits and Gen 2 follow. |
| 2015–2021 | Rhino axle line, Terminator and Assassinator tire lines, XR Optic hard coating and the Off-Road Atlas content library all mature. Net sales reach $211 million in fiscal 2021. |
| Aug 17, 2022 | Dorman Products (NASDAQ: DORM) announces a definitive agreement to acquire SuperATV. Sellers are Harold Hunt, Damon Stephan and Lindsay Hunt. |
| Oct 4, 2022 | Deal closes. Dorman pays $490 million in cash plus an earn-out of up to $100 million tied to 2023 and 2024 performance targets. Dorman finances it with a five-year $500 million incremental term loan. |
| 2022–2025 | Lindsay Hunt, SuperATV's CEO before the acquisition, leads Dorman's new Specialty Vehicle segment through integration. |
| May 19, 2025 | Kathleen Pacheco is named President of Dorman's Specialty Vehicle segment in a planned succession. Lindsay Hunt moves to an advisory role. |
| 2026 | Atlas Pro A-Arms launch with 1.5" tubing, 50% larger than stock. XR Optic hard coating gets a reformulation measured at 3.9 times the scratch resistance of the previous formula. |
SuperATV is a wholly owned subsidiary of Dorman Products, Inc., a publicly traded aftermarket parts supplier headquartered in Colmar, Pennsylvania, and in business for more than 100 years. SuperATV operates as the core of Dorman's Specialty Vehicle business segment.
Three things worth knowing if you are weighing SuperATV against a smaller brand:
Manufacturing stayed in Madison, Indiana. The routing, welding, cutting, milling and assembly work still happens at the same facility. Products are still tested on the company's own machines before release.
Warranty is now backed by a public company. Dorman's balance sheet stands behind a lifetime portal warranty in a way that a private single-owner manufacturer's cannot. That matters most on the parts with the longest coverage.
The founding family stepped back. Harold Hunt founded the company and sold it in 2022. Lindsay Hunt ran it through the transition and is now advisory. If you see a page still calling Harold Hunt the "current president," that page has not been updated since 2022.
We started carrying SuperATV parts in 2012, and we drove down to Madison to meet them not long after. The whole operation ran out of a small square office. You could stand in one spot and see everybody working. Harold was there. Lindsay was there. Damon Stephan was there. We sat down with them in 2013 and again in 2014, and what stuck with us was that the people making the decisions were the same people who rode the machines and answered the phone.
Ten years later Dorman Products paid $490 million in cash for that company, with an earn-out that could carry the total to $590 million.
We bring that up for one reason. We have watched this brand's parts come back and not come back for 14 years now. We know which lines they fixed, which products got quietly discontinued, which warranty terms they honor without an argument, and which ones require a phone call. That is not something you learn from a catalog feed. It is why the fitment answers on this page are ours and not copied from a spec sheet.
From the shop: the single most common SuperATV return we process is an axle ordered for the wrong trim. Axle length changes inside the same model year across trims on several Polaris and Can-Am platforms, and the machine's model name alone will not get you there. Send us the year, model, trim and whether the machine is lifted. Two minutes on the phone saves a 30% restocking fee.
SuperATV product names get thrown around like everyone knows them. Here is what each one actually is.
| Name | What it is |
|---|---|
| GDP (Gear Driven Performance) | The portal gear lift division. GDP portals raise the machine without lifting the chassis and add gear reduction at the wheel. |
| Rhino / Rhino 2.0 | The core axle line. 4340 chromoly steel, aggressive angle tolerance. |
| X300 | The premium axle tier, built from 300M alloy steel. Three-year warranty. |
| ADR | Direct 1:1 OEM-replacement axles in 4340 chromoly. The value tier. |
| Rhino Driveline | Prop shafts and driveline components, including the Bounty Series. |
| XR Optic | The proprietary UV-cured hard coating applied to polycarbonate windshields and doors. |
| Terminator / Terminator MAX | Aggressive all-terrain mud tires. MAX is the lighter, upgraded lug pattern. |
| Assassinator | Dedicated deep-mud tires. Three-inch tread depth, wide lug spacing, sizes to 37". |
| Intimidator | Mud-capable all-terrain tires with heavy siping. Two inches of shoulder tread. |
| Warrior / XT Warrior | All-terrain tires for mixed riding. |
| SandCat | Dune and sand tires. |
| Black Ops | The winch line. |
| Rack Boss | Rack and pinion steering assemblies. 1.0 and 2.0 generations. |
| Portal Blood | 80W-90 gear oil formulated for GDP portal boxes. |
| EZ STEER | Steering assist products. |
| REV1 | Clutching and drivetrain performance. |
| Dual Idler® | A portal configuration with a second idler gear that spreads load across roughly twice the surface area. |
Assault Industries — steering wheels, mirrors, cages and interior hardware. GBoost Technology — clutch kits and drive belts. HCR Racing — long travel and mid travel suspension kits. HCR trades under Super ATV, LLC and its affiliates, and runs the same 90-day return policy. Keller Performance Products — heavy-duty ball joints and steering components, carrying a lifetime warranty. Up & Running — replacement and maintenance parts: brakes, fuel pumps, O2 sensors, starters, prop shafts, tie rods, U-joints, rack and pinions.
Cardo, Garmin, MTX Audio, Motobatt and Rugged Radios sit under their "Brands We Trust" banner. Warranty on those runs through the original manufacturer, not SuperATV.
Axles are SuperATV's highest-volume hard part, and the four lines are genuinely different products rather than trim levels of one product.
| Line | Material | Warranty | Replacement fee | Best for | What you give up |
|---|---|---|---|---|---|
| ADR | 4340 chromoly | 1 year, manufacturer defect only | None published | Stock-height machines, direct OEM replacement | No coverage for breakage from riding, only defects |
| Rhino | 4340 chromoly | 1 year | Free within 60 days, then $50 flat | Lifted machines, aggressive trail and mud riding | Shorter coverage window than 2.0 |
| Rhino 2.0 | 4340 chromoly | 18 months | Free within 60 days, then $50 flat | High-angle setups, portal and lift kit builds | Costs more than standard Rhino |
| X300 | 300M alloy steel | 3 years | $100 flat, unlimited replacements in the term | Big tires, portals, hard mud, anyone who breaks axles | Highest price in the line |
How to read that table. The X300 warranty is the real differentiator. Three years with unlimited $100 replacements means a rider who snaps two axles a season comes out ahead against a cheaper axle with no breakage coverage. The Rhino 2.0's 18 months at $50 is the middle ground most buyers land on. ADR covers defects only, so if you break one on a hill climb, that is on you.
One thing the spec sheets do not tell you: boots are excluded from every axle warranty in this line. Running a torn boot until the CV grenades is the most common way riders void coverage they already paid for. Check boots at the same interval you check tire pressure.
Portals are the product that put SuperATV on the map. The 4" GDP kit launched in 2015 and the design has gone through several generations since. A portal box relocates the wheel hub below the axle centerline, which adds ground clearance without raising the chassis or changing suspension geometry, and the gear set inside multiplies torque before it reaches the wheel.
| Reduction | Available in | Tire size it suits | Ride character |
|---|---|---|---|
| 15% | 4" kits | 30"–33" | Keeps close to factory top speed, modest torque bump |
| 30% | 4" and 6" kits | 33"–35" | The balanced pick. Big torque gain, noticeable RPM increase at speed |
| 45% | 6" and 8" kits | 35"–37" | Heavy mud and rock. Real top-speed loss |
| 60% | 6" and 8" kits (model dependent) | 37"+ | Bounty hole builds |
| 70% | 8" kits | 40" | Dedicated mud machines |
Available reductions vary by machine. Some 6" kits list 30/45/60 rather than 30/45. Check the reduction options on your specific model's product page, and use SuperATV's portal calculator if you are between two numbers.
Cast or billet housing. Billet is machined from solid aluminum and costs more. Cast handles normal trail and mud duty.
Single or dual idler. The idler is the only gear in the box touching two others, so it absorbs the most load. Adding a second idler spreads that load across roughly twice the surface area. Gears are 9310 steel alloy, precision CNC ground so both idlers actually share the work rather than one carrying the set. If you run big tires and heavy throttle, dual idler is the upgrade that matters.
From the shop: the single most common portal warranty denial we see traced back to gear oil. GDP boxes take 80W-90 gear oil, and SuperATV sells Portal Blood formulated for them. Packing a portal box with grease instead of oil will cook the gears and bearings, and it explicitly voids the lifetime warranty. There are no vents in the box by design.
SuperATV has shipped more than 150,000 windshields, and the spec that drives that volume is material choice.
Quarter-inch polycarbonate. Rated 250 times stronger than glass and 25 times stronger than acrylic. In practice that means a branch that would crack an acrylic windshield bounces off.
The tradeoff polycarbonate carries. It is soft. Untreated poly scratches from the grit in mud you wipe off with a rag.
XR Optic hard coating. SuperATV's answer is a proprietary hard coating, UV-cured on their own coating line rather than thermally cured in an oven. The formula was reworked and lab-tested at 3.9 times the scratch resistance of the previous version. Glass still beats it, by a factor of about 3.6, but the gap between coated poly and glass is now smaller than the gap between the new coating and the old one.
What to buy. Full windshields for cold-weather and dust. Half windshields divert air over your head while keeping the open-cab feel. Flip and vented windshields give you three positions from the seat, which is the right answer for anyone riding across seasons. Rear windshields stop the dust rotor that pulls cab air backward and fills the cab.
Windshields are covered for one year, plastic or glass. Doors in poly carry one year and metal, aluminum or plastic doors carry 90 days.
| Tire | Tread depth | Ply | Built for | Tradeoff |
|---|---|---|---|---|
| Terminator | 2" | 6 | Mud plus trail. Center lug rides smooth on hard surfaces | Less bite than Assassinator in deep mud |
| Terminator MAX | 2" | 6 | Same mission, better cleanout, roughly 10 lb lighter per tire than competing mud tires | Costs more than standard Terminator |
| Assassinator | 3" | 6 | Deep mud only. Wide lug spacing, sizes to 37" | Loud and rough on hard-packed trail |
| Intimidator | 2" shoulder | 6 | Rocks, hills, gravel, snow, sand. Heavy siping | Not a dedicated mud tire |
| Warrior / XT Warrior | — | — | All-terrain daily riding | Not built for bounty holes |
| SandCat | — | — | Dunes | Single-purpose |
Load ratings run by size. A 30x10-14 Intimidator carries 485 lb at 7 PSI. Terminators run 585 lb at 7 PSI. Terminator MAX in larger sizes is rated 1,610 lb at 20 PSI. All of these carry a built-in rim guard.
Tire warranty across the line is 90 days, and mounted wheel-and-tire combos are also 90 days.
This is the reference riders ask for most and almost nobody publishes in one place. All terms run from date of purchase, to the original purchaser, with proof of purchase required.

Several categories carry a replacement fee rather than free replacement. Rhino and Rhino 2.0 axles ship free inside 60 days, then $50. X300 axles are $100 flat and can be replaced as many times as needed inside the three-year term. Prop shafts are free inside 60 days, then $75. Differentials, transmissions and portals inspected and found to be outside coverage are repaired for a $250 fee.
Coverage is void for misuse, unauthorized accessories, alteration, improper installation, missing or tampered stickers, and lack of maintenance. Bearings, seals, gaskets, boots, bushings and rotors are wear items and excluded across the board.
Manufacturer-direct warranty applies to MTX, Garmin, Cardo and DynoJet products.
The budget entry. Wear and maintenance parts, tie rods, boot kits, mirrors, bulbs and grilles land in the $20 to $100 band. Up & Running replacement parts, brake pads and fuel pumps sit here too. This is honest, functional hardware without the premium warranty attached.
The sweet spot. Most SuperATV buyers land between $200 and $700. That covers windshields, doors, roofs, bumpers, skid plates, winches, single axles, cargo racks and most lighting. The build quality is the same as the top of the line, and the parts carry real one-year coverage.
The premium tier. Portal gear lifts run $2,000 to $3,000 and up depending on lift height, reduction and idler configuration. Long travel kits, complete differentials, full lift kits and mounted tire-and-wheel sets sit in the $1,500 to $4,500 range. These earn the price through the limited lifetime warranty and the fact that they change what the machine can do rather than just how it looks.
The most common warranty is between 3–6 months, but Side By Side Source does offer extended 1- and 2-year warranties on all products if that is something you are interested in. You can add the extended warranty right at checkout. SuperATV's own manufacturer terms above run alongside that, not instead of it.
Financing is available through Affirm at checkout, which is worth knowing on a portal kit.

Fitment inside a family is not universal. Defender and Defender MAX split on anything cab-related. RZR portal kits change by generation. Axle length varies by trim within a single model year. Send us your year, model and trim and we will confirm before you order.
Worth knowing before you buy direct. SuperATV publishes return terms in three places and the three do not fully agree, which is the single most common source of frustration we hear about.
The version on their Returns Policy page runs a sliding scale. Unopened, resalable, in original packaging, returned within 30 days is a full refund. Inside 60 days is a 10% restocking fee. Inside 90 days is 20%. Nothing is accepted past 90 days.
The version on their Return Policy page describes a 90-day return with no sliding scale, provided the item is new, unused and in original packaging.
The version in their Terms and Conditions of Sale states a minimum 25% restocking fee plus a possible $20 repackaging fee, depending on condition.
Consistent across all three:
Buying the same part through us instead means one return policy rather than three, and we handle the manufacturer conversation for you.

Where is SuperATV made? Madison, Indiana. The address is 2753 Michigan Rd, Madison, IN 47250, a river town on the Ohio with roughly 12,000 residents and a manufacturing base that goes back generations. Routing, welding, cutting, milling and assembly all happen there. Some component sourcing is global, as it is across the entire aftermarket, but the manufacturing operation is Indiana-based.
Who started SuperATV? Harold Hunt founded the company in 2004. He came out of a global operations role at Rotary Lift and studied at Indiana State University's Scott College of Business. He was also a creek rider, which is where the first lift kit came from.
Who owns SuperATV now? Dorman Products, Inc. (NASDAQ: DORM), a publicly traded aftermarket supplier based in Colmar, Pennsylvania. Dorman announced the acquisition on August 17, 2022 and closed it on October 4, 2022, paying $490 million in cash plus an earn-out of up to $100 million tied to 2023 and 2024 performance. SuperATV had posted $211 million in net sales in fiscal 2021. SuperATV now anchors Dorman's Specialty Vehicle business segment, led by President Kathleen Pacheco since May 2025.
Is SuperATV still family-owned? No. It was family-owned and family-run from 2004 until October 2022. Harold Hunt, Damon Stephan and Lindsay Hunt sold to Dorman. Lindsay Hunt, who had been CEO, ran the Specialty Vehicle segment through integration and moved to an advisory role in 2025. Manufacturing stayed in Madison. Any page still describing SuperATV as family-owned or naming Harold Hunt as current president is out of date.
What does UTV stand for? Utility Terrain Vehicle, sometimes called a side-by-side or SxS. UTVs seat passengers side by side, carry cargo in a bed and are built for work as much as recreation. An ATV, or all-terrain vehicle, is the straddle-seat quad you steer with handlebars.
Who manufactures Rhino axles? SuperATV designs and manufactures them in-house. Rhino, Rhino 2.0, X300 and ADR are all SuperATV product lines, not sourced from an outside axle maker.
Are aftermarket SuperATV parts as good as OEM? OEM is one well-made option at one price in one material. The aftermarket gives you that quality level from multiple makers, usually at lower cost, in materials and configurations the factory does not offer. SuperATV's quarter-inch polycarbonate windshield is rated 250 times stronger than glass, and their A-arms carry a lifetime warranty that no OEM A-arm matches. Where the aftermarket wins hardest is the niches: portal gear lifts, 37-inch mud tires and plow systems are products no OEM builds.
What is the difference between Rhino and Rhino 2.0 axles? Both are 4340 chromoly. Rhino 2.0 carries 18 months of coverage against the standard Rhino's 12, and it is engineered for the steeper suspension angles that come with lift kits and portals. Both cost $50 for a replacement after the first 60 days.
Do GDP portals need special gear oil? Yes. Use 80W-90 gear oil. SuperATV sells Portal Blood formulated for the boxes. Using grease will destroy the gears and bearings and voids the lifetime warranty.
How long does SuperATV take to ship? SuperATV runs regional warehouses and most lower-48 orders arrive in two days or less from their own site. Ordering through us, most items ship within 24 hours from our 12 warehouses, and any exceptions show a lead time right on the product page.
Does SuperATV offer a military discount? Yes, through their Frontline 5 program for military and first responders. Terms are set by SuperATV and apply on their own site.
How many products does SuperATV launch a year? The company has historically cited more than 600 new products annually, and their customer service team is trained on every launch. Treat the exact figure as a moving target.
Can I return a SuperATV part? Yes, inside 90 days. SuperATV's own terms tighten as the window gets longer, and restocking fees run from zero inside 30 days up to 30% on made-to-order items. Special-order items such as hand-held ECU tuners are non-returnable, and pulling the protective film off a polycarbonate windshield or roof ends its eligibility. Buying through us puts one policy between you and the return instead of three.
Does SuperATV own HCR Racing? Yes. HCR Racing operates under Super ATV, LLC and its affiliates and builds long travel and mid travel suspension kits. Same 90-day return terms.
How long have you carried SuperATV? Since 2012. We met the team in Madison when the company still ran out of one small office, sat down with Harold Hunt, Lindsay Hunt and Damon Stephan in 2013 and 2014, and have carried the line every year since. Fourteen seasons of watching which parts come back and which ones do not is the reason our fitment answers are our own.
What is SuperATV's phone number? Main line is 812.574.7777. Customer service and returns run through 855.743.3427, and the warranty department is 855.728.8256, Monday through Friday, 8am to 5pm EST.
