Tech Insight
A 1-1/4" shank rod end delivers a massive increase in strength, fatigue resistance, and durability for vehicles that push suspension components to their limits. The included 1" to 3/4" high angle spacers allow builders to retain common 3/4" mounting hardware while benefiting from the strength of a larger bore rod end.
This setup is ideal for rigs with extreme suspension loads, long travel, and high shock forces—where smaller rod ends simply aren’t an option.
Pairs perfectly with 7075 aluminum links or heavy-wall steel links in competition-level builds.
