- Outperforms factory and all other aftermarket style tie rod ends by offering a larger shank with no stress riser (doesn't neck down at base), preventing premature failure
Features:
- Fully greaseable sintered metal on metal bushing design has high wear resistance
- Precision engineered grease grooves in the OD of the induction heat treated ball bearing
- Ultra-strong forged bearing housing made from 1018 steel
