 Product Description

Call us Prior to ordering this system as you must ship your shocks to us.


By far one of the best selling UTV’s on the market, the RZR XP 900 combines a great suspension design with 88 horsepower to create an excellent performing package. The XP 900 come with Fox Podium shocks or Walker Evans shocks as an option including a 2.5″ diameter rear shock that performs very well out of the box. But, Polaris places criteria on  Fox and Walker Evans which tie their hands a bit when it comes to ride potential. They must set the RZR up for the worst case scenario ( from a ride perspective ) such as two 300 lb guys and a roof rack full of gear. Because of this the XP900 is set up way on the stiff side.  All of the chop, rocks and wash board roads transfer straight through the chassis into the drivers seat and rattling your teeth. In addition to that if you drive in the dunes and turn the compression up for the big G outs the small chatter gets much worse. Our Stage 1 Ride Improvement System (RIS) cures all of this and more.  By modifying the piston to improve and manage oil flow as well as change the valving and increase oil flow through the compression adjustor we can virtually eliminate all of the small chop and vibration transfer into your seat as well as increase the bump stage which stops the RZR from bottoming out in the G outs. This makes it you don’t even need to turn the compression up for the dunes keeping the ride even smoother. With the stock set up a one hour drive through rough terrain may leave you feeling beat up and worn out.  After the Stage 1 RIS you can run all day without that feeling.  Your wife and passengers will thank you. Your friends will be jealous of your plush ride as well as slower than you through the roughest terrain. Our customers report 25 to 35% ride quality improvements with our Stage 1 RIS. Don’t wait, unlock the smooth ride potential in your RZR and become the fastest guy in your UTV group!
