BMR Suspension Red Torque Box Reinforcement Plate Kit for 1979-2004 Ford Mustang (TBR004R)

Fits 1979-2004 Ford Mustang models including Base, GT, LX, SVT Cobra, SVO, and Bullitt.

Fox-chassis Mustangs are notorious for chassis fatigue when subjected to high torque loads. The factory torque boxes—the critical mounting points for the upper and lower rear control arms—are prone to cracking or even ripping away from the floor pan. This structural failure leads to poor rear-end alignment, unpredictable handling, and unsafe driving conditions. The BMR Suspension Torque Box Reinforcement Plate Kit (TBR004R) provides a heavy-duty solution to stiffen this area and prevent structural failure.

Constructed from CNC-laser cut, CNC-formed steel plate and high-strength DOM steel tubing, this kit is designed to bolt directly into the 1979-2004 Mustang chassis. By reinforcing both the upper and lower control arm mounts, it ensures your suspension geometry remains consistent under load, allowing you to launch harder and put more power to the pavement without risking damage to the chassis.
