Overview

The UMI Performance Upper and Lower Control Arm Reinforcements Kit strengthens the rear control arm mounting points on the Ford Mustang. This upgrade prevents damage caused by high torque and improves durability, supporting aftermarket control arms and polyurethane bushings. It is an essential reinforcement for enthusiasts seeking improved rear suspension reliability. Manufactured from 3/16" mild steel, components are precision laser cut and welded to ensure structural integrity. The kit arrives in bare metal form, ideal for welding, and requires painting after installation. Grade 8 hardware is included for a secure fit.

Part #: 1001

If you have raced your Mustang aggressively, on slicks, or even on the street and especially if your car is a 5-speed, you may have cracked torque boxes. Fox bodies don't have the best chassis to begin with, combined with a V8 and some torque, and you are going to have problems. That is why lower control arm reinforcements or torque box reinforcements were designed to reinforce weak and cracked torque boxes (front lower control arm mounting point).
