2014-21 Ranger 570 Stage 1 Lock & Load Kit

The Aftermarket Assassins Stage 1 Lock & Load Kit pairs an AA tuned Dynojet Power Vision with the AA S1 Recoil clutch kit for the Polaris Ranger 570. The factory 45 HP motor is held back by torque limits, low speed limits and a timid rev limit, and this kit unlocks another 5 to 7 HP.

Why it holds up

• Level 1 makes 52 to 53+ HP on 91 octane when properly clutched, or around 50 HP on the 87 octane timing curve
• Factory 50 MPH high and 24 MPH low speed limits removed, with speeds around 60 MPH in high gear
• Rev limit raised to 8000 RPM, torque limits removed, and fan temps lowered to 195 on and 185 off
• Clutching brings RPM up to 7500 to 7700 where the motor makes peak power
• The Power Vision reads the ECU before tuning to confirm the correct tune is loaded

• A valet or kid mode tune is available only for newer TBW models, with a 35 MPH limit and 50% throttle that can be customized.
• Custom race fuel tunes are available on request.
• Ships within 24 to 48 hours of purchase because each tuner is custom programmed.
• The tuner views and erases most trouble codes, logs 25 parameters for review on a Windows computer, and returns to stock easily.
