Tech Insight

Running a 1-1/4" shank rod end with a full 1" bore provides the highest strength and shear capacity available in a traditional four-link rod end setup. This configuration is ideal for extreme vehicle weights, high shock loads, and aggressive suspension geometry where stepping down bolt size is not desired.

With a narrower installed width than stepped-down spacer options, this kit is also well-suited for tight packaging where bracket spacing is limited but strength cannot be compromised.

Pairs perfectly with 7075 aluminum suspension links or heavy-wall steel links in competition-level builds.
