The Aftermarket Assassins Stage 4 Lock & Load Kit pairs the AA big turbo with PV3 tuning, S3 clutching and high flow parts for the 2021 and newer RZR Pro XP, Turbo R and Pro S. Built engines on race gas or ethanol can reach 320 to 330 crank horsepower, and it still trail rides on Level 2.

Why it holds up

  • Larger than stock compressor wheel and housing pushes more air per turbo RPM
  • Larger exhaust housing with high flow turbine for less backpressure and lower EGT
  • High pressure billet wastegate actuator with new stainless steel bracket
  • Each turbo blueprinted and balanced with new bearings by a professional turbo manufacturer
  • Billet BOV replaces the weak stock unit, and the high flow charge tube replaces a stock tube known to blow out at Level 3 and up

Fits

  • 2021 and newer Polaris RZR Pro XP, 2 and 4 seat
  • 2022 and newer Polaris RZR Turbo R and Pro S
  • Does not fit 2020 Pro XP models

In the box

  • AA big turbo with AA billet wastegate, cylinder head to turbo gasket, exhaust outlet bolts and drain tube o ring
  • PV3 tuner with 1 AA tune plus the stock tune
  • S3 clutch kit, butter shift washers and clutch limiter
  • Billet BOV with filter, exhaust and charge tube
  • Post airbox intake tube (standard or catch can version)
  • Pre gapped iridium spark plugs

Good to know

  • The standard post airbox intake tube suits Level 2 to 3. The catch can version is suggested for Level 4 to 6.
  • Clutch kit includes a setup guideline for weights by tire size and tune level, for 29 to 35 inch tires.
  • Tunes disable throttle by wire and seat belt limiters, remove the speed limiter in low and high, add throttle and boost in low and reverse, set fan on/off at 185 F (stock 190) and set rev limit at 9,300 RPM.
  • Start in any gear: the machine does not need to be in park, but press the brake to start or it may throw a code. This removes a safety feature.
  • The PV3 plugs into the diagnostic port, so the ECU never has to be sent in. It also reads and clears most trouble codes and data logs 32 parameters for review on a Windows computer.
  • Iridium plugs are included because these models have had low power issues from bad plugs.
