Description

The UMI Performance 4034-B is a rear sway bar designed for 1964-1972 GM A-Body vehicles. It aims to improve handling by reducing body roll and understeer, enhancing cornering capabilities.

The sway bar is constructed from a 1-inch solid 4140 chromoly steel that is heat-treated and formed as a single piece for maximum strength and performance. This manufacturing process helps the sway bar retain its shape and memory longer than cold-bent alternatives. The product includes new Grade 8 hardware for installation.
