8.75 Rear End Disc Brake Conversion

the jeep rotors you need to get would be front vented ones off the box style cherokee, NOT grand cherokee, as those are 6 lug. the boxy small cherokee rotors are 5 bolt 4-1/2" circle a 3" setback, and a 11" diameter and are the same rotor weather its 2WD or 4WD. i should know i just bought a set to do my rear axle. they also slide right onto an 8-3/4" rear axle without trimming or modifying them.

i am going to buy a set of the speedway motors GM style rear calipers with integral park brake. they run $159 a pair brand new complete with pads and pins. the speedway motors weld on caliper mounts for these are 1/4" steel plate and are $9.99 each. i got my rotors used for $15.00 each out of the junk yard, but new they are only about $23.00 each so it wont really break the bank to buy em new anyways.

so for less than 200 bucks you can have 11" diameter rear discs and a killer WOW factor. i also picked up a set of 2-3/4" diameter piston calipers, caliper brackets, 12" rotors and dust shields off a 1978 chrysler cordoba. believe it or not these parts are a direct bolt in on the 73 to 76 A body spindle. i got all this for under $100 along with my cherokee rotors at $15 each. a killer haul, but more importantly i will have a killer 4 wheel disc brake setup for around $350 when all is said and done.
