Polaris RZR S/Trail S 1000 Stage 1 Lock & Load Kit by Aftermarket Assassins

Description

Fits all 2016-Up Polaris RZR S 1000 & Trail S 1000 models

Unlock the full potential of your Polaris RZR S 1000 with the Stage 1 Lock & Load Kit by Aftermarket Assassins. Designed for riders who demand instant throttle response, increased horsepower, and optimal clutch performance, this kit delivers a complete performance upgrade in one precision-engineered package. Whether you’re tearing through trails, climbing dunes, or powering through deep mud, this system ensures consistent power and reliable performance under every condition.

This Stage 1 kit combines advanced ECU tuning with a high-performance clutch setup to create unmatched power gains. The included Powervision ECU tuner comes preloaded with Aftermarket Assassins’ proven performance tunes, allowing you to easily flash your factory ECU, switch between tunes, and restore stock settings whenever needed. The tuner’s built-in gauge display provides real-time data such as throttle position, timing, and engine performance, helping you monitor your machine with accuracy. Enhanced data logging and diagnostic features let you analyze performance and clear trouble codes on the go.

Each tune is expertly calibrated to deliver stronger mid-range torque, faster throttle response, and higher top-end power while maintaining safe, reliable operation. The optimized fuel and timing maps remove factory limitations, disable throttle-by-wire restrictions, and eliminate speed and seatbelt limiters. A lowered fan activation temperature and raised rev limit ensure improved cooling and extended performance at higher RPMs. Choose between Level 1 tuning for stock exhausts or Level 2 for upgraded systems, both offering significant horsepower gains and smoother power delivery.

The Stage 1 clutch kit complements the tuning upgrade by transferring power directly to the wheels with maximum efficiency. Adjustable magnetic clutch weights, custom-cut helix, and precision-tuned springs deliver responsive acceleration and consistent RPM control. Riders can select between Standard Load (ideal for 27–30” tires and trail riding) or High Load (for 31–32” tires, dunes, or mud). Engine braking options allow you to retain or remove EBS based on your riding style, and the optional “Cruiser” setup offers quieter operation and lower cruising RPM for relaxed trail performance.

Every kit includes the AA custom-tuned PV3 tuner, AA Recoil adjustable clutch weights, primary and secondary springs, custom helix, and detailed setup instructions. Engineered through extensive real-world testing, this package ensures peak performance, improved drivability, and long-lasting reliability for your Polaris RZR S 1000. Experience next-level power, smoother engagement, and superior throttle precision with a kit built by riders, for riders.
