what size wheel spacer

[74LIFE]

I bought the complete offroad 1 ton steering system i have 15" x 14" alcoa's with 3-3/4" backspacing. what size wheel spacer would keep rims from coming in contact with tre.

Typically 3.5" is what you need to clear, but every wheel is a little different. That's some serious leverage with 14" wide wheels!

Crap.

Im going to be using 15" wheels with 4" of backspacing. Early Bronco drum brake knuckles with Chevy disc swap. I assume i cant run the GM TRE's flipped? Am i going to have to use heims instead?

Is it the drum EB knuckles that have the clearance issue or is it the disc EB/F150/ Big Bronco knuckles?

You may be able to slide by if you're running drum knuckles. those chevy's are huge and when you go TRO it's a tight fit

I just mounted one up and there is tons of room with the drum knuckles and 4" backspacing wheels. The TRE would have to be about 5" in diameter before it rubbed the wheel. There is a little over 1.5" between the top of the knuckle arm and the wheel lip.

Im guessing most of the clearance issues is with the disc brake knuckles.

The Eb drum knuckles are usually ok with 4" backspacing, you may need to watch the caliper to wheel clearance depending on the wheel design. I had a steel 15x 8 w/ 4" bs spare that won't fit over the front caliper after Chevy disc swap. The caliper mounting bracket/dust shield needed some slight clearancing to clear 15" x 10" Eagle 589 3.75" BS only on one side.

Stack washers and keep doing a trial fit until they clear. Then measure the thickness of the stack of washers and order shims that thick.

Might want to keep some spare wheel bearings and ball joints handy with that much tire that far out from the axle.
