What does this kit do for my RZR's suspension?

This kit replaces the knuckle on your RZR's rear independent suspension. It includes bushings designed to reduce friction and wear, helping to restore proper suspension function.

What makes the bushings special?

The bushings are made from self-lubricating acetal nylon, which helps them wear better and perform more smoothly over time compared to standard bushings.

Are there any other parts needed for this repair?

This is a knuckle-only kit, meaning it focuses on replacing the knuckle and its associated bushings. You may need to reuse other suspension components or purchase additional hardware depending on the condition of your existing setup.
