60 Axle HD Ball Joint Kit Upper & Lower - Set Of 4 (part number 3452030).

TeraFlex HD Ball Joints are engineered to handle the increased loads caused by oversized tires, added vehicle weight, and offset wheels. They feature a threaded ball stud retaining ring that replaces the factory's crimp-style design, which is notorious for failure. This ring also allows precise preload adjustment during assembly and later, on-vehicle adjustments using basic hand tools eliminating the need for costly, labor-intensive rebuilds.

Each TeraFlex 60 Axle HD Joint incorporates a massive 32mm heat-treated chromoly ball stud and a hardened tool steel wear plate for maximum durability. Dual helical grease grooves machined into the stud allow spent grease to exit through a low-profile seal, improving longevity and simplifying maintenance. From serious trail abuse to daily driving, these ball joints deliver long life, consistent performance, and easy, on-vehicle adjustability that eliminates the need for rebuilding.
