Can you think of a part that can ruin your day quicker than a knuckle if it breaks? When you’ve got trees whizzing past on either side of you, a cracked spindle can lead to a catastrophe. Get our Billet Rear Knuckles for the Polaris RZR XP 1000 and get unprecedented strength and an eye-catching billet finish that you love.

We use 7075-T6 billet aluminum to make these spindles, where stock uses 6061. The yield strength of 7075 is 73,000 psi, which is nearly double that of 6061’s 40,000 psi yield strength. What can you do with double the strength? Keep the pedal down twice as long, hit jumps that are twice as big, and have twice as much fun.

These spindles work with any suspension you’ve got whether it’s stock, SuperATV, or anything else. It’s also compatible with your stock wheel bearing for easy service and replacement. It matches stock geometry perfectly so you can simply bolt it up and ride. We also eliminated unnecessary material to give it more clearance for your suspension. You get a smooth installation and a smooth ride.
