Fabtech uniball upper control arm kit replaces the factory upper arm with a uniball-equipped assembly for 2011–2018 GM C/K2500HD and 3500HD 2WD/4WD applications. The arms use a stainless uniball bearing and chromoly tubing to reduce flex, add caster for improved alignment, and allow increased wheel travel when paired with Dirt Logic 2.5 coilovers. They fit as direct replacements for added strength.
