2021 RZR Turbo & Turbo S Stage 1 Lock & Load Kit

The Aftermarket Assassins Stage 1 Lock & Load Kit combines AA custom tuning on a Power Vision 3 with an S3 clutch kit for the 2021 Polaris RZR XP Turbo and Turbo S. AA notes the factory 2021 clutching slips the belt, so the clutching turns the added power into wheel power.

Why it holds up

• Tune adjusts boost, timing and hundreds of parameters for safe power gains
• All tune levels disable throttle by wire limiters, lower fan temps to 185°F and remove speed limiters in low and high gears
• Rev limit at 9200 RPM, more throttle in low gear and a less sensitive over boost code
• Clutching turns the added power into wheel power instead of just RPM

Fits

• 2021 Polaris RZR XP Turbo and Turbo S, all models
• Does not fit older turbo models

In the box

• PV3 tuner loaded with one AA tune
• S3 clutch kit
• Butter Shift washers
• Primary clutch limiter
• Iridium spark plugs

Good to know

• Best paired with the Level 2 or Level 3 tune. Two tunes are recommended, especially at Level 3 or higher.
• Level 2 runs 16 to 16.5 PSI for a 10 to 12 RWHP gain. Level 3 adds 20 to 25 RWHP at 17 to 17.5 PSI and needs an aftermarket exhaust and clutching.
• Level 3 and higher tunes need the wastegate rod shortened 2 turns
• Revolver clutch plate or AA HD primary clutch upgrades are kit options. The HD primary requires the P90X clutch puller.
• A stock 2021 RZR Turbo dynos at 135 to 138 RWHP on the AA dyno
