2021-Up RZR Pro XP/Turbo R/Pro S Stage 3 Lock & Load Kit

The Aftermarket Assassins Stage 3 Lock & Load Kit combines PV3 tuning, S3 clutching, exhaust, billet BOV, charge tube and intake tube for the 2021 and newer Polaris RZR Pro XP, Turbo R and Pro S.

Why it holds up

• AA tuning changes boost, timing and hundreds of parameters for safe, big horsepower gains.
• The exhaust greatly reduces back pressure so the tune can run more boost.
• Clutching turns that power into wheel power instead of just RPM.
• The billet BOV replaces the weak stock valve, and the high flow charge tube replaces a stock tube known to blow out at Level 3 and higher.
• Iridium plugs are included because these models have had low power and bad plug issues. Fresh, longer lasting iridium plugs have been the cure.

Fits

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

In the box

• PV3 tuner loaded with AA custom tunes
• S3 clutch kit
• Butter Shift Washers
• Clutch limiter
• Billet BOV with filter
• Exhaust
• Charge tube
• Post airbox intake tube, or intake tube with catch can
• Iridium spark plugs, pre gapped

Good to know

• Intake tube comes in two versions: standard for Level 1 to 3, or with catch can for Level 4 to 6.
• 2021 and newer models have a different helix design and do not need the pre airbox intake tube.
• Base kit includes the single muffler exhaust, with an upgrade available to the quieter Dual Suppressor Exhaust.
• Clutch kit includes a setup guideline for weights by tire size and tune level. Works with 30 to 35 inch tires and 30 to 33 inch paddles.
• AA tunes disable the throttle by wire limiters and the seat belt limiter, remove the speed limiter in low and high gears, add throttle and boost in low gear and reverse, and set the rev limit at 9300 RPM. Fan comes on and off at 185 degrees Fahrenheit (stock is 190) and ramps up quicker to keep the engine cool.
• Start in any gear is optional. The machine does not need to be in park to start and will start without the brake but throws a code. This removes a safety feature.
• The PV3 plugs into the diagnostic port, so the ECU never has to be sent in. It checks and erases most trouble codes and data logs 32 parameters with one push of a button for review on a Windows computer.
• One tune plus the stock tune is included. AA recommends two tunes so you can drop to a lower level if fuel quality is poor.
• Tune Levels 1 to 4 are built for the stock wastegate setting and stock injectors. Levels 5 and 6 require AA 1200cc injectors and a wastegate rod adjustment.
• Level 3 runs 18.5 to 19 PSI on 91 to 93 octane for a 20 to 25 RWHP gain and requires the high flow pre airbox intake tube, exhaust, billet BOV and S3 clutch kit.
• A stock machine dynos at 156 to 158 RWHP (181 crank HP per factory).
