Common Questions
What makes Keller Ball Joints different from stock?
Keller uses a two-piece, snap-ring-free design with a threaded chromoly housing that pinches the A-arm, preventing push-through failure unlike stock ball joints.
Are these suitable for lifted RZRs?
Yes, their robust design and durable materials are specifically engineered to handle the stresses of larger tires and lifted suspension setups.
How do I maintain them?
Keller Ball Joints are adjustable and greaseable, allowing for easy maintenance to ensure long-lasting performance and a smooth ride.
How many ball joints do I need per vehicle?
This product is sold individually. Typically, a vehicle will require four ball joints (two upper and two lower). Please check your vehicle's specific needs.
What Riders Are Saying
These ball joints are seriously beefy. I haven't had a single issue since installing them, and my RZR is lifted with 32-inch tires. Worth every penny to avoid the hassle of stock failures.
— Mark S., Colorado
I was constantly replacing ball joints on my old setup. Since upgrading to Keller, I've had zero problems. The peace of mind alone is fantastic. Installation was straightforward too.
