Description

Improve performance and eliminate upper A-arm deflection on your 1964-1972 GM A-Body with a set of Upper A-arms from BMR's suspension! Factory A-arms and bushings can wear out over time and cause deflection, resulting in changes in alignment and reduced performance on the track and street. BMRs Non-Adjustable Upper A-arms (AAU401) greatly improve steering feel and response and are designed for street performance, drag racing, handling, and pro-touring applications. When performance is a must, rely on BMR's suspension!
