Product details
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 we 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 and DOM steel tubing, 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. This kit includes the tubular braces and hardware to reinforce the upper control arm mounts, and the plate style lower control arm mounts. Torque Box Reinforcement Plate Kit (TBR005 And TBR003)
