With 21 years of documented research and development in the forced induction field, AMS Performance has proven itself as the powerhouse in the automotive aftermarket. Our award winning performance systems are what all others are measured by.

The AMS Performance R8/Huracan DL800 Reinforced Differential Cover & Transmission Brace has been developed as a solution to excessive case flex during high horsepower launches that can cause damage to transmission internals. As the case flexes, it can cause a misalignment of components like the ring and pinion gears, leading to failure. Our cover and bracing solution creates three additional mounting points for support bracing arms that greatly increase the structural rigidity of the entire three piece transmission case.

  • 6061-T6 Billet Aluminum and 4130 Chromoly Steel Material
  • Increased Case Rigidity to Keep Alignment of all Transmission Internals
  • Lightweight and High Tensile Strength
  • Hardware Capable of Being Reused Unlike OEM Torque-to-Yield Aluminum Bolts
  • Direct Fit Install – Completely Reversible


Engineered to Win

Our AMS SnailWorks© Engineering Team has spent countless R&D hours refining the AMS Performance R8/Huracan DL800 Reinforced Differential Cover & Transmission Brace to be the best performing, highest quality, and easiest to install kit on the market. Utilizing real world data, our engineers were able to calculate force acting upon the differential cover and ring and pinion gear set to allow us to simulate the force on our reinforced design. Instead of just recreating the stock cover in billet, our team ran a simulation to verify the best way to create structural improvements.
