Here is a quick fact about the RZR RS1: the rear radius arms do a lot of work. They help locate the rear wheels through every bump, landing and hard corner. After enough miles, the bushings that let them pivot start to wear, and that wear shows up as slop.
When that happens, the Rebuild Kit for SuperATV Polaris RZR RS1 Radius Arms, available at Wild Boar ATV Parts, puts fresh parts back where the old ones have worn out.
Signs your radius arms need attention
SuperATV puts it plainly: when your radius rods start to move in their bushings, it is time. Other signs riders notice include clunks from the rear over bumps, a back end that feels loose or wanders, and uneven tire wear. Jack the machine up and check for play by hand. If the arms shift where they should be snug, the bushings have had enough.
What comes in the kit
The kit includes one brace plate, 8 inner bushings, 8 outer bushings and the hardware to put it together. The brace plate is 3/16-inch thick steel, and the bushings are zinc-plated chromoly steel. That gives you everything needed to refresh the wear points in one order instead of piecing parts together.
Why rebuild instead of replace
If the arms themselves are straight and in good shape, there is no reason to throw them away because the bushings are tired. A rebuild kit restores the pivot points for a lot less hassle than replacing the whole arm. It is the same idea as replacing worn ball joints or wheel bearings: fix the part that wears, keep the part that does not.
Riders who push their RS1 hard should check suspension pivots regularly, especially after big hits or a season of rough trails. Catching wear early helps protect other parts and keeps the machine tracking straight. A clean, greased, tight suspension also just feels better under you.
Check what arms you have
This kit is made for SuperATV’s radius arms on the Polaris RZR RS1. Before ordering, confirm that is what is on your machine. If you are not sure which arms you have or what you need, call the Wild Boar team and we will help you figure it out.
