Product details
If you have raced your Mustang aggressively, on slicks, or even on the street and especially if your car is a 5-speed, you may have cracked torque boxes. Fox bodies don't have the best chassis to begin with, combined with a V8 and some torque, and you are going to have problems. That is why lower control arm reinforcements or torque box reinforcements were designed to reinforce weak and cracked torque boxes (front lower control arm mounting point). The torque box area is the front mounting point of the lower control arm. This area is a must for reinforcement when running any kind of aftermarket control arm, polyurethane bushings or UMI lift bars. Lift bars are well known for tearing stock torque boxes from the car. Reinforcements will fix already cracked and torn mounting points as well as reinforce unharmed points. Installation: Reinforcements are Weld- or Bolt-in and install in approximately 2 - 2½ hours. All hardware and installation instructions are included with each kit. 1020 - 1979-2004 Ford Mustang Lower Control Arm Reinforcement
