The steering braces are constructed from 0.250 in. 1018 mild steel CNC-machined mounting points and 1.250 in. DOM steel tubing with a 0.120 in. wall that is fully MIG-welded for extreme strength and lasting performance.

UMI Performance control arm torque box reinforcements will take care of those cracked torque boxes. 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; combine them with a V8 and some torque, and you are going to have problems. That is why control arm reinforcements or torque box reinforcements were designed to reinforce weak and cracked torque boxes.
