This is a custom differential cover I designed for use on the Datsun 510 using a Subaru R180 differential. Possible fitment on Subaru Sti models also. Carved from solid billet 7050 aircraft aluminum. Near mirror finish, all edges radiused or chamfered. Fill and drain are -8 o-ring boss ports. This allows easy expansion to a full on diff cooler setup if needed. Utilizes the factory plastic subaru vent which is baffled by the oe Subaru gasket. Very stiff internal structure should add a little extra rigidity to the diff case. Holds roughly 1/3 more oil than a standard cover.
Ships with a Subaru gasket, vent, XRP -8 ORB internal hex plugs, and new flange head bolts. Raw machined aluminum finish.
Ships without any engraving, engraving available at additional cost.
