Polaris RZR 900 Heavy Duty Ball Joints (Kit of 4)

Heavy Duty Ball Joints — Kit of 4
This kit of 4 Heavy Duty ball joints gives you a complete set for the Polaris RZR 900. Each joint features heat-treated internals, tighter machining tolerances, and a 4340 chromoly stud — everything you need to replace all four ball joints at once and restore your suspension to better-than-factory condition.

Do the Job Once
If one ball joint is worn, the others are not far behind. A full kit of 4 lets you replace every ball joint in a single session — consistent handling, balanced geometry, and no repeat teardowns.

Built for Sport Riding
The 4340 chromoly studs handle the higher speeds and harder impacts that sport UTVs demand. Heat-treated housings resist deformation under aggressive cornering, jumps, and rough terrain. These are the ball joints your RZR 900 deserves.

Direct Fit
Each joint is engineered for the Polaris RZR 900 suspension and drops in using factory hardware — no modification required.
