About this part

Product Details

When you're putting serious power down in your 1979-2004 Ford Mustang, the factory torque boxes can become a weak point. These areas are known to crack and rip under high torque loads, leading to alignment issues and potential chassis damage. This kit from BMR Suspension is designed to beef up those critical upper and lower control arm mounts, giving you the confidence to apply as much power as you want to the wheels.

What you get in this kit are the tubular braces that reinforce the upper control arm mounts, along with the plate-style reinforcements for the lower mounts. Everything is made from CNC-laser cut, CNC-formed steel plate and DOM steel tubing, then finished in a tough Black Hammertone coating. These parts are designed to bolt directly into your Mustang's chassis, adding significant stiffness and strength to a common failure point on the Fox chassis.

Reinforcing the torque boxes is a smart move for any Mustang owner looking to increase power or simply ensure the longevity of their chassis. It's a solid way to protect your investment and ensure your rear suspension stays properly aligned, no matter how hard you drive.
