Keller Ball Joint Polaris Pro R / Turbo R
- 4340 hardened chromoly steel construction
- Two-piece threaded design doesn’t require a snap ring
- Easily adjustable, rebuildable, and greaseable
- Robust boot retaining ring prevents water intrusion
Keller Ball Joints are made with hardened 4340 chromoly steel. They’re fully greaseable and adjustable, so they’ll last basically forever with proper maintenance. And the two-piece design ensures a secure fit that won’t come loose. Long story short, OEM ball joints can’t hold a candle to Keller. Lesser ball joints rely on a snap ring. But those snap rings are liable to break at the most inconvenient times—but not Keller Ball Joints. The housing threads onto the A-arm so there’s no snap ring at all. Run big lifts and huge tires through rough terrain with no worries. In fact, these could be the last ball joints you ever buy!
