Alloy rear diff case for Spitfire MkIV, 1500, GT6 MkIII and other swing spring applications (4 stud case only).

A more economical cast and machined alternative to our CNC billet alloy diff cases.

Increased oil capacity and finned for cooling, also includes drilling for drain plug.

Straight replacement for cast iron original and approximately a third of the weight!

Please Note!

High material and machining costs mean that it's simply not possible to make the CNC billet version of the diff cases and sell them at a reasonable price. We will not be making them again, so please don't ask!
