UMI’s a-arm kit is built to offer increased rigidity, smooth travel, a precise steering feel, and an 8lb weight savings over stock. This kit features a combination of our race lower a-arms and street upper a-arms, makes for a great drag race oriented a-arm kit that is easy on the wallet. The DOM 1-1/4” diameter tubular sections are precision bent, CNC notched and welded in a jig to form the solid base. In-house built 4130 chromoly tube adapters on the lower a-arms provide a durable attachment point for the premium Teflon lined race quality rod ends. The strong fabricated upper a-arms use street friendly greasebale polyurethane bushings. The spring and shock attach to the lower arm via a tough 1/4” thick steel shock mount.
