Super Duty Converted Diff Housing
This is for the out right purchase of a converted diff housing. No need to send us yours.
MX5 / Miata differential casings are prone to snapping. More torque from a turbo or supercharger conversion, more mechanical grip or simply hard driving and launches can lead to a failure.
Mounting without the Mazda Power Plant Frame (PPF) also seems to make the failures more common. For this reason we highly recommend this modification when the diff is to be mounted in a kit car.
This diff housing has had the following work:
Press out old bushings
Bead blast the casing to look like new
Weld on our billet CNC machined diff bracings
