This kit disperses the acceleration loads evenly throughout the rear of your Mustang.

This Kit Includes:
- Torque Box Reinforcements
- Torque Box Plates (2)
- Mounting Bolts (8)
- Nylon Locking Nuts (8)

Please Note: This Lower Torque Box Reinforcement Kit is a Bolt-in installation but should be welded in place for a better result.
