Lock and load your RZR RS1 and get ready for some serious kick! The RZR RS1 is a great machine, but Polaris left a ton of room for improvement on any year machine. This simple kit is the best way to wake up your RS1 as it comes with our proven ECU tunes which are loaded via the PVCX ECU tuner. The tunes add some amazing horsepower from low end to high end RPM's, and really give your machine that "snap" you're looking for. The clutching compliment the tuning perfectly by better transferring the power to the wheels and ridding yourself of the very lazy factory clutching setup.

The Level 1 tune is a huge increase and is meant to be ran with the stock exhaust. This is seriously worth every penny! You are looking at a 6-7 RWHP gain with the tune and 8-9 RWHP when used with our S3 clutch kit. Peak power is excellent with this setup but the bottom end gained might be even better! Peak power is 8600-8800 RPM @ 55 MPH
The level 2 tune has all the same benefits as level 1, with increased fueling for a slip-on or full exhaust system. Together with a tune and exhaust you can see 8-10 RWHP gains, and 2-3 more RWHP when used with our S3 clutch kit! Peak Power is 8600-8800 RPM @ 55 MPH
Either tune is available with a slightly hotter timing curve for 95 or higher octane fuel. This tune will increase horsepower another 2-3rwhp, and provide better bottom end torque.

Wicked throttle response and quicker back shifts when in/out of the throttle
More consistent clutch performance
Adjustable clutch weights (magnetic adjustable) with a great setup guideline
We offer two clutch kits: Performance Helix & High Load Helix:
The Performance Angle is what 90% of users will want. It offers great power transfer to the wheels that will take off and keep pulling hard. Use this with tires 27" to 32" and you will adjust with the weights to make up for different tire sizes.
The High Load Angle is for those using very large tires. The High Load helix is recommended for those turning 34" tires or 31-32" paddles. The High Load helix can be used with any tire size 29" and greater if you are just after belt life and performance is not your priority. The Performance angle can still be used with the larger tires and paddles if all out performance is what you are after, just keep in mind belt life will be less than with our High Load setup.
