This kit includes the minimum parts you need to make some serious power! No matter if you ride trails, mud, or dunes, we know your RZR 900 needs more power. From the factory, they are sluggish because of the heavy clutching and ECU tune that does not allow full RPM or even full throttle. We fix that by adding our performance tune which opens the throttle 100% and removes torque limiters. It also removes the soft and hard rev limit so we can increase the rev limit to 8600 RPM. Fuel and timing adjustments are also made to improve overall performance. Our Stage 1 clutch kit includes our Goldstar magnetic adjustable primary weights and a custom BMP primary spring. These simple clutch changes allow the motor to rev much higher than factory to where the real power is made. For even better results, purchase our Stage 1 Bolt-On Performer kit which upgrades your exhaust and secondary clutch (coming soon).
**Please Read** Turf Mode Issue - If your RZR 900 came with 1 wheel drive, it will be disabled with this kit.
