UMI's tubular upper and lower a-arm kit replaces worn factory stamped a-arms on G-Body and S10 platforms with high-strength construction and Delrin bushings throughout. A slightly relocated ball joint mount adds clearance for lowered vehicles while a relocated upper mounting pad increases caster without extra shims.

UMI Performance 303233 Features:

• 8 lb weight savings over the factory a-arm set.
• UMI-built Delrin bushings in both upper and lower a-arms for low-deflection handling.
• 4140 CrMo cross shafts, CNC machined and zinc plated.
• Relocated upper mounting pad increases caster without excessive shims.
• Jig built and TIG welded for a consistent, accurate fit.
• Premium ball joints preloaded in both arms.
• Works with factory springs, lowering springs, and coilover kits such as QA1.
• Red or black powder coat finish.
• Manufactured in Philipsburg, PA, USA.
