9" Ford rear end, 9 or 11 1/1 to one gear ratio.

it is a limited slip rear end if you are wondering why it does 1 wheel burn outs

the '52 should have a 4.11:1 ratio in it currently. If you change it out for the '54 rear end you will have a 3.55:1 ratio. As far as changing it, it should bolt right up. Do you have a more specific question?

There is 2 big u-bolts on each side of the rear end that hold the rear end housing to the spring pads, sounds like they have broke on 1 side.
