Looking for all-out performance out of your 800 Axys? With an impressive 20.6 gain in horsepower and 9.4 ft/lb increase in torque, this kit is sure to satisfy. The heart of this kit is SLP porting of the cylinders and exhaust valves. This is combined with our highly sought after single pipe set complimented with match porting and internal ceramic coating on the inside of the stock y-pipe. Special SLP Power Dome™ heads are used and they too have ceramic coating on the domes to enhance performance. An SLP Reflash Tuner is used to modify the stock ECU programming and provide the proper fuel and ignition to optimize this combination on 91 octane pump fuel (0-3000’ 91 octane pump fuel plus SLP recommended octane booster). The clutching is also changed with the addition of SLP weights and SLP springs (drive and driven). These clutching changes allow all the extra horsepower and torque to be transferred to the ground effectively and efficiently. This is the ultimate gas, oil, and ride combination.

Available for ALL elevations.

Requires Cylinders, EV Assembly and Y-Pipe be sent in for modification.

This season I set out to make the lightest Polaris Axys RMK possible. As part of the weight loss plan, I went with the SLP Stage 4. Hands down my favorite thing about the Stage 4 is the throttle response. It’s so quick down low, which I love for tree riding. It is also an animal on the top-end. This set up pulls 4 more grams of weight in the primary clutch which is HUGE...especially up at my elevation of 11,000 ft+.  - Chris Burandt
