    I'm not sure if I need calipers for 13X2.5" or 13X3 3/8".

    I'm not even sure what the second number is measuring, thickness?

    I'm trying to buy calipers and rotors and these numbers keep coming up. It's a SRW D60. /forums/images/graemlins/thumb.gif

    I believe those measurements are referring to the rear shoe dia x width.

    I always that that the calipers were the same for a GM D60 regardless of SRW or DRW application. /forums/images/graemlins/confused.gif /forums/images/graemlins/dunno.gif

    Me to. It's probably the parts guy trying to figure out through is parts "program" if your rig has a D60 front or a 10 bolt ... that would be the only time the rear shoes would differ.

    Tell him you have to 13" x 3 1/2" rear shoes.

    You need the 13 x 3-1/2 units (JB8 brake pkg). The 13 x 2-1/2 are 3/4T units (JB7 brake pkg). One tons only used the 13 x 3-1/2 rear brakes.

    BTW, SRW and DRW calipers are the same. The only difference between brake parts is the rotor on a DRW has different diameter holes to mount it to the DRW hub asm than the SRW has for the wheel studs to go through (rotors are the same otherwise). Other than the hole diameter differences everything is the same between SRW and DRW.

    These are new ones for me. What's a SRW and a DRW, I can't even fathom? /forums/images/graemlins/confused.gif

    SRW = single rear wheel

    DRW = dual rear wheel
