One of the most frustrating experiences for any 6 Speed Supra owner and drag racing is the financially painful breaking of the cast differential cover! Eliminate this forever with a billet aluminum perfect fitment upgrade.

There are no custom modifications required, fitment is perfect.

From our manufacturer’s point of view, they created this cover for Supra owners with high horsepower applications that are tired of breaking/replacing their flimsy cast OEM differential covers.

Our Billet covers are C.A.D. designed and programmed on the greatest 3D software. We then start with *Certified* 6061-T6 Aircraft Grade Billet Aluminum. Our covers are precision milled on our state of the art CNC machines; utilizing solid carbide tooling.

The whole cover is one solid piece of aluminum, no welding, for added strength and durability. Once off the machine, the cover is dimensionally inspected by our quality department, which is ISO 9000 compliant.

It only leaves the manufacturing facility if ALL features are within specifications. Included is a Grade 8 bolt kit, for a totally bolt together installation.
