The Aftermarket Assassins Stage 1 Lock & Load Kit pairs the AA ECU flash with the AA Stage 3 clutch kit for the 2024 and newer Polaris RZR XP 1000. It adds power across the RPM range and fixes the lazy factory clutching and poor belt grip.

Why it holds up

  • Throttle by wire limiters disabled, seatbelt limiter removed and speed limiter removed in low and high gear
  • Fan on/off at 185/180 F (stock is 205/192), just above thermostat opening temp
  • Rev limit at 9200 RPM (stock is 8800), with ideal peak RPM of 8400 to 8600 at 55 MPH
  • Start in any gear with the brake, and more throttle in low and reverse
  • Timing tuned for ramp up and torque, with fuel corrected over the factory lean AFR at higher throttle

Fits

  • 2024 and newer Polaris RZR XP 1000
  • 2026 and newer RZR XP 1000 S (72 inch wide)
  • Works with Dynamix and EVAP models

In the box

  • AA ECU flash for the 2024 and newer RZR XP 1000
  • AA Stage 3 clutch kit with primary clutch limiter

Good to know

  • The Bosch MG1 ECU must be sent in for programming unless you buy a new ECU outright
  • Level 1: bone stock XP 1000 on 91 to 93 octane. Adds +5 RWHP (6 crank HP), roughly 120 crank HP
  • Level 2: aftermarket exhaust on 91 to 93 octane. Adds +7 RWHP peak and +9 RWHP at 30 MPH, roughly 125 crank HP
  • The ECU sits behind the driver seat (rear driver side on 4 seat models). Remove the top panel behind the seats, then the Torx bolts and connector
  • To check for an EVAP model, see the Emissions Control sticker on the front driver side frame rail above the front shock
