Unmatched Strength and Performance for Your Can-Am Defender

Upgrade your Can-Am Defender with the ultimate suspension solution—Mega Keller Ball Joints by SuperATV. Engineered for riders who push their machines to the limit, these heavy-duty ball joints deliver superior strength, unbeatable reliability, and long-lasting performance on every terrain. Built to handle extreme off-road abuse, they’re perfect for lifted rigs, oversized tires, and the most demanding trails. When your adventures call for durability beyond stock components, Keller’s Mega Ball Joints are the upgrade that keeps your Defender performing flawlessly.

Engineered for Maximum Durability

These ball joints are precision-machined from premium 4340 hardened chromoly steel, providing exceptional tensile strength and resistance to wear. The oversized housing accommodates a larger stud and the industry’s biggest ball, giving you enhanced load-bearing capacity and eliminating the weak points found in OEM joints. The robust two-piece threaded design ensures the joint stays securely in place—no snap rings, no failures, just rock-solid performance ride after ride. Each component is designed to resist corrosion, reduce friction, and extend service life, making them ideal for both recreational and professional use.

Innovative Two-Piece Design

Todd Keller’s original two-piece threaded design revolutionized ball joint technology. By threading the housing directly onto the A-arm, these joints create a mechanical lock that prevents push-out and pull-out, even under extreme pressure. This innovative system ensures maximum retention and stability, allowing you to conquer rough trails, deep mud, and rocky climbs with total confidence. The greaseable and adjustable design also allows for easy maintenance, letting you restore factory-tight performance whenever needed.

Perfect for Lifted and Modified Setups

If you’ve installed a lift kit or upgraded to larger tires, Keller’s Mega Ball Joints are the perfect match. The oversized components eliminate the common weaknesses of stock joints, giving you uncompromised steering control and suspension articulation. With these installed, you can take on aggressive terrain, heavy loads, and high-speed rides without worrying about joint failure.

Key Features

  • Massive studs and housings for superior strength and durability
  • 4340 chromoly steel construction for extreme toughness
  • Two-piece threaded design eliminates the need for a snap ring
  • Fully greaseable, adjustable, and rebuildable for extended service life
  • Heavy-duty boot retaining ring keeps out dirt and water
  • Ideal for lifted or oversized tire setups

Note: Mega Keller Ball Joints require modification of your A-arms for installation. For riders who demand uncompromising performance, this upgrade delivers the ultimate combination of durability, precision, and strength for your Can-Am Defender.
