SDI is proud to offer its suspension services for the UTV Market. We take your feedback and what you expect out of suspension and put it into a service package to meet that demand. Not everyone needs every upgrade, or just needs valving, or even just springs. Based on your comments on our form, we suggest what would work best for the situation.

For RZRs, we offer:

Performance Piston Upgrades (Valving)
Click Here for Valving Upgrades
Performance Piston Kits make it easy to give your RZR’s Walker Evans shocks a valving setting that targets the environment and driver’s ability. Easy to drop in and install, the kits are available in two settings, Performance for those more aggressive trail and dune drivers, and Race, for soaking up the obstacles, jumps, and bumps of a course at high speed.

Shock Shaft Upgrade

Get the most out of your RZR XP1000’s (2 seater) Walker Evans Rear shocks by getting one of the shaft upgrade kits. Each kit contains a 7/8ths stainless shaft and seal head to replace the 3/4ths, performance or race piston kits, and necessary spacers. Giving your shocks added durability, and performance from the upgraded valving and piston.

Crossover Rings

Give your RZR a true dual rate spring set up.
These easy to install rings adjustable up and down the shock body to set when the second rate starts to work. Without these on your shock, you simply have a single combined spring rate through the shock. Why settle for the stock single rate, when a simple add on gives you more control.

High/Low Speed Adjusters
Click Here for High/Low Speed Adjusters
The SDi High/Low Speed adjusters are a game changing suspension modification, allowing you to tune your car to your needs more precise than stock. Like suspension on a motocross bike, the adjuster uses clicks to tune, with separate High & Low speed adjusters, preventing crossover between the settings.

Springs

Whether you added weight to your RZR, not carrying as many passengers as expected, or want the suspension to operate in a certain way, Springs are an easy solution. We stock several options, and can gladly order whatever maybe needed.

Additionally, as a distributor for the top manufacturers, replacements parts, such as seal kits or complete seal heads are readily available. If a particular part is needed, but not stocked, we can locate and order it.
