Product Description

The BMR Suspension TBR004R Torque Box Reinforcement Plate Kit is a premium chassis strengthening upgrade engineered for **1979-2004 Ford Mustang Fox-Body** vehicles. When large amounts of torque are applied to a Fox-Body Mustang's chassis, the factory torque boxes - the mounting points for the rear control arms - are prone to cracking or flexing. This kit adds robust upper and lower reinforcement plates that significantly increase chassis rigidity, reduce control arm mount deflection, and help prevent torque box failure under hard launches, high-power street driving, or aggressive handling situations.

Designed with precision-cut and formed steel plates and finished in a durable red powdercoat, the TBR004R installs via a **100% bolt-on design** using the supplied hardware. While the plates are ready to go out of the box, some enthusiasts elect to weld them in final position for additional reinforcement in racing or high-stress applications. Ideal for anyone reinforcing their Fox-Body Mustang for drag, street, or handling use, this reinforcement plate kit enhances the rear suspension's durability and allows more power and torque to be applied to the wheels without damaging critical chassis components.
