Overview

The BMR Suspension TBR001 is a torque box reinforcement plate kit designed for 1979-2004 Ford Mustangs. These braces are made from CNC-laser cut, CNC-formed steel plate to reinforce the upper and lower control arm mounts. This kit addresses known issues with the Fox chassis, where factory torque boxes can crack under high torque, leading to alignment problems and poor performance.

The TBR001 kit includes braces and hardware for installation. While they bolt in, welding is recommended for extreme power applications or dedicated racing use. The product comes in a bare finish and is proudly made in the U.S.A. Installation time is estimated at 4-5 hours.
Show original supplier description
The BMR Suspension TBR001 Torque Box Reinforcement Braces are engineered to strengthen the critical torque box area of the 1979-2004 Ford Mustang chassis. The factory torque boxes on the Fox-body Mustang are known to be a weak point, prone to cracking and ripping under significant torque loads. This structural compromise can lead to rearend alignment issues, compromised performance, and potentially unsafe driving conditions. This added strength allows Mustang owners to apply maximum power and torque to the wheels with greater confidence, preventing damage to this vital chassis component. The TBR001 is suitable for street performance, drag racing, and handling applications. Installation time is estimated at 4-5 hours and requires minimal fabrication. For vehicles producing extreme amounts of power or used primarily for racing, welding the braces in place is recommended for maximum reinforcement. The kit includes all necessary braces and hardware. The product features a bare finish and is proudly made in the U.S.A. BMR Suspension emphasizes that fitment should always be confirmed. If there are any concerns about fitment, it is recommended to contact their team before placing an order or initiating a return. If BMR's sales team recommends an incompatible setup or makes an order error, they will work with the customer to resolve the issue, potentially waiving restocking or return shipping costs for items in like-new condition. Returns must be approved and initiated within specific timeframes, and items must be returned in new, unused condition with all original accessories.
