Torque Solution Billet Aluminum Differential Brace is made of a single piece of high-grade CNC'd 7075 billet aluminum. We chose 7075 aluminum due to its high strength, toughness, and good resistance to fatigue. You can rest assured knowing you are getting a high-quality part that will last. With the addition of this brace, you will see and feel an improvement with wheel hop being reduced and better traction. The brace helps prevent failure of the factory rear diff bushing by reducing drivetrain movement and preventing harmful damage to your rear differential. Works with stand OEM diff cover, Nismo diff cover, as well as other aftermarket diff covers. The design of the brace is unique as it adds a solid diff support directly to the rear subframe utilizing a preexisting hole!! We include all necessary hardware to complete the install.
