The Stage 2 Lock & Load Kit for the 2021 Can-Am Maverick X3 RR is engineered to deliver impressive horsepower and torque gains, transforming your UTV into a high-performance machine ready for any terrain. Designed exclusively for the 2021 X3 RR equipped with the MG1 silver ECU and 6-arm primary clutch, this precision kit is not compatible with 2022+ models featuring the P-Drive clutch. Every component in this system works together to maximize power, response, and reliability, offering a noticeable performance boost without compromising drivability.
This kit includes a comprehensive combination of upgrades—custom AA ECU tuning via the HP Tuners RTD4 device, clutch calibration, and exhaust improvements. By increasing boost pressure and optimizing fuel delivery, the ECU tune unlocks the full potential of your engine. The refined clutching setup enhances RPM ramp-up, letting your Maverick reach higher operating speeds quickly and efficiently where maximum power is achieved. The included exhaust system reduces backpressure, lowers heat buildup, and maintains consistent boost levels for longer, more aggressive runs.
With the HP Tuners RTD4, owners can flash the ECU directly using an iPhone or Android device through the HP Tuners TDN app. The kit also provides data logging, diagnostic code reading, and clearing capabilities for complete control and insight into vehicle performance. The ECU unlock process is handled by HP Tuners in Illinois, ensuring professional calibration and security. Both standard and express unlock services are available depending on your preference and turnaround needs.
Included in the package are the AA S2 clutch kit, HP Tuners RTD4, OBDII to Can-Am diagnostic port cable, ECU unlock service, and all necessary tuning credits. One custom AA tune is provided, with additional tunes available for those wanting to fine-tune power delivery based on fuel type or supporting modifications. Expect quicker throttle response, improved acceleration, and smoother power delivery across all drive modes. The throttle mapping is refined to make sport mode more responsive while maintaining control in lower modes and low-range gear for crawling or utility use.
When paired with the Level 3 tune, this kit provides significant horsepower gains, making it ideal for riders seeking extreme performance from their Can-Am Maverick X3 RR. For those looking to take it further, adding a blow-off valve and catch can—featured in the Stage 3 Lock & Load Kit—can enhance efficiency and reliability under high-boost conditions. The Stage 2 Lock & Load Kit is your key to unlocking the full potential of your 2021 X3 RR, giving you faster spool times, stronger midrange pull, and sustained top-end power that holds through the RPM range. Built for enthusiasts who demand more from their machines, this performance upgrade delivers power, precision, and durability in one complete package.
