Teraflex 3442022 Heavy Duty Ball Joint Set - with Knurling for 07-18 Jeep Wrangler JK

The TeraFlex Heavy Duty Ball Joint Set for Jeep Wrangler JK is engineered for Jeep owners who demand superior steering performance and long-lasting durability, whether on the road or tackling the toughest trails. Manufactured with premium materials and advanced design, these ball joints address the common wear issues found in factory joints, offering tighter tolerances, smoother operation, and improved serviceability. TeraFlex offers two options for the JK: the non-knurled version (3442002) for Jeeps with factory knuckles that are still within spec, and the knurled version (3442022) for knuckles that have been stretched or previously fitted with knurled ball joints. Both sets deliver the strength and reliability that serious off-roaders and daily drivers alike depend on.

Notes:

• We recommend ball joints without knurls as they will not score the inner knuckle and open up the bore.
• We also offer ball joint with knurls for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed previously.
