Benefits:
- Engineered with grease grooves in the ball bearings, achieving the longest lasting metal on metal rod end on the market with maximum lubrication and wear resistance
- Eliminating the nylon ball race allows for a larger ball bearing and increased strength
- The spring loaded bearing design keeps pressure on the bearings and the joint tight as it wears, preventing premature play
- 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
- Spring loaded bearing design keeps pressure on bearings and keeps the joint tight as it wears
- Tie Rod End stud made from 4140 steel with an extra large shank
- Heavy duty nitrile-butadiene rubber (NBR) boots and retaining springs
- DynaFlo 1/4′-28 straight steel zinc grease zerk fittings with ball check
Notes:
- These tie rod ends are replacements for Synergy MFG steering bars only – please refer to fitment table to ensure product fitment; They will not replace a factory steering linkage end
- Synergy High Performance Grease is the recommended grease for this product
- Single Plane tie rod ends offer misalignment in one direction of movement only. This eliminates drag link flop on the products they are designed for
- Zerk specs: DynaFlo 1/4′-28 straight steel zinc grease fittings with ball check
