Aftermarket Assassins '21 Can-Am Maverick X3 RR 195 HP Stage 2 Lock & Load Kit w/ RTD4 & ECU Unlock
Lock & Load! This Stage 2 kit provides a big increase in horsepower and torque in a simplified package. Increased boost, clutching, and exhaust on the X3 work together for major power gains to the wheels. The AA custom ECU tuning via RTD4 delivers strong performance depending on tune level, supporting mods, and fuel choice, while clutching helps the engine reach higher RPM where peak power is made. The exhaust reduces heat and back pressure, helping support higher and more consistent boost levels.
The 2021 X3 RR already performs well, but this kit unlocks significantly more potential. Factory boost delivery is improved with quicker spool and better high-RPM retention, allowing the clutching to hold the engine in the optimal power range. The system also improves throttle response and drivability while maintaining safety parameters for the engine and turbo charger.
