Overview

The UMI Performance ABR401-B is a rear control arms kit designed for 1965-1967 GM A-Body vehicles. This kit replaces stock control arms, which can contribute to traction loss and poor handling, with tubular upper and lower control arms, rear end housing bushings, and Grade 8 hardware.

The lower control arms feature greaseable bushings and reinforced sway bar provisions, while the adjustable upper control arms allow for pinion angle optimization. The components are constructed from 1.500" x 0.120" DOM tubing with TIG/MIG welded construction for superior strength and finished with a durable powder coat.
