Beef Up Your Knuckles
If you like to ride solo on your
RS1, you need to know you and your machine can get through anything. Upgrade
to SuperATV’s Billet Rear Knuckles for the Polaris RZR RS1, and be confident
knowing that they give you unmatched strength for a more reliable ride.

Virtually Two Times Stronger than Stock
aren’t ordinary spindles, they’re made with 7075-T6 billet aluminum which
outperforms your factory knuckles easily. The yield strength of 7075 is 73,000
psi–nearly double that of the 6061’s 40,000 psi yield strength on stock.
Whether you’re racing or adventuring, all that strength means you can count on
them to survive the ride.

Excellent Compatibility

We made these knuckles to match OEM specifications so that any suspension
setup you have will fit. We even trimmed down some unnecessary material from
stock specs to improve fitment and range. Basically, we made installation as
easy as possible, no matter what you’ve got on your RS1.
