FAQ

How do I know my RZR 570 rear suspension bushings are worn?

Clunks over bumps, side-to-side play when you rock a rear wheel, uneven rear tire wear, or squeaks from the A-arm pivots are the usual signs.

What comes in the kit?

All Balls lists four Delrin bushings and two needle bearing shafts per kit.

Which models does it fit?

All Balls lists Polaris Ace 900 XC (2017-2019); Polaris RZR 570 (2012-2020); Polaris RZR Trail (2021-2022); Polaris Diesel (2015-2018); Polaris Diesel (2015-2018); Polaris Ranger Crew XP 1000 (2017-2018); Polaris Ranger Crew XP 570 (2015-2025); Polaris Ranger Crew XP 900 (2014-2019); Polaris Ranger Midsize (2014-2021); and more, see the full fitment list below.

Is installation difficult?

The rear A-arms and knuckle come off so the old bushings and shafts can be pressed out and the new ones pressed in. A press or bushing driver and your service manual torque values are needed. All Balls does not publish an install sheet for this kit.

Does it fit the front or rear?

All Balls lists this kit for the rear independent suspension on the machines it covers.

Do I need the full rear suspension kit?

This kit covers the knuckle side only. If the A-arm bushings are also worn, the full All Balls rear independent suspension kit rebuilds the A-arms and knuckle together.
