4.22 Differential


Well-Known Member
Been waiting to test it and now have done and have a 4.22 differential that slots straight into a Commer back axel, simple upgrade. Should allow people to reach a good top end without breaking your ears or drop the van down on 14” wheels and slimmer tyres without compromising current top end. With my OD, 14” alloys and slimmer tyres I’m confident of doing 70mph now at about 3200 revs which is right near the top torque.
There’s a lot of confusion about what they come from between the supersnipes and Hawks but this is a Hawk one with a smaller crown wheel, I think fitted to the later models.
