Torque Box Reinforcement Plate Kit - Hardware Included - Steel - Natural - Ford Mustang 1974-2004 - Kit

Reinforcement Kit

Increase stiffness and reinforce the torque boxed in your 1979-2004 Mustang with Torque Box Reinforcement Braces from BMR's suspension. The Fox-chassis Mustangs were not known for being super strong. When large amounts of torque are applied to the Fox chassis, the factory torque boxes are known to crack and rip. This causes all kinds of rearend alignment issues, poor performance, and unsafe driving conditions. Designed from CNC-laser cut, CNC-formed steel plate, BMR's Torque Box Reinforcement Braces are designed to bolt into the 79-04 Mustang chassis, adding strength to the upper and lower control arm mounts. This means you can put as much power and torque to the wheels as possible, without fear of damaging this critical area of the chassis.

Additional Information

This kit includes the braces and hardware to reinforce the upper and lower rear control arm mounts (torque boxes).

Reference Information

Torque Box Reinforcement Plates, Upper/Lower Rear, Steel, Natural, Ford, Kit

BMR Suspension torque box reinforcement plate kits offer strength and performance benefits for your Fox-chassis Mustang—which are not known for being strong. These kits will increase stiffness, reinforce the factory torque box, reduce control arm mount deflection, and deliver the ability for added horsepower and torque to be applied safely to your Fox chassis. The reinforcement braces for the upper and lower rear control arm mounts (torque boxes) are made from CNC laser-cut, CNC-formed, and MIG-welded steel plate. The plates bolt in using supplied hardware and require very little fabrication to complete. BMR kits are available for lower or upper only, or together. Prevent rear-end alignment issues, poor performance, and unsafe driving conditions—while putting as much power to the wheels as possible, without fear of damaging the critical area of your chassis—by adding BMR reinforcement plate kits.
