The Mooresport Inc. R180 Rear Differential Cover is a pure work of art, carved from a nice chunk of billet T6-6061 aluminum. This is a 100% CNC machined piece that is stronger than comparable cast examples, and come delivered smooth right out of the manufacturing process with no rough surfaces.
The design includes multiple provisions for AN-08 adapters for options such as external oil coolers, pumps, and it comes with a standard 1/8-NPT temperature sensor housing.
Other features include a 1/16" groove for a Viton O-ring cord. The factory breather is transferable to the new cover, and it holds 20% more oil capacity over stock.
