    Did a search, but didnt find what I was looking for. I have a 3/4 ton axle that I'm about to bolt up to my Jimmy and was wondering if the 1/2 ton calipers will work on the 3/4 ton axle?

    this is only part correct. the 3/4 with the 13" rear brakes had a bigger piston, the 3/4 ton with the 11" rear brakes have the same size pistons as the 1/2 ton.

    they bolt up the same

    Yes they are. I just installed them on a 3/4 ton setup.

    they will all bolt up, but if you have a bigger piston and then go to 1/2 ton calipers you are losing braking power with the smaller piston
