Get a Better Knuckle
Breaking a knuckle on your RZR Turbo is bad news. Not only is your ride ruined, but we’re guessing you’re also going pretty fast when that thing pops, which means you’re piling up on the trail. Instead of replacing a busted knuckle with the same stock part that broke on you, upgrade to SuperATV’s Billet Rear Knuckles for the Polaris RZR XP Turbo. You’ll get unprecedented strength backed by a head-turning billet finish.

Virtually Two Times Stronger than Stock
We beef up our spindles by making them with 7075-T6 billet aluminum which beats the heck out of the factory knuckles. The yield strength of 7075 is 73,000 psi, which is nearly double that of 6061’s 40,000 psi yield strength. When you have double the strength, you can ride twice as hard. The competition better watch their back.

Total Compatibility
These rear knuckles are built to match OEM specifications exactly so you can fit any rear suspension setup you want. We even eliminated unnecessary material to make fitment better. No matter what you’re doing, installation will be easy, and the ride will be smooth.
