15s on 80 axles (1 Viewer)

[White Stripe]

Has anyone fit 15's on 80 axles. I have heard with trimming of the caliper on the rear you can fit em. But I can't find a write up of how to do it and what wheels it works with and what it doesn't. IE steel only or aluminum, and what backspacing.

15s came standard on the 80s prior to 93. 93 and later had a different brake caliper and 16 inchers. Depends totally on what year truck your axles are from/on.

can't tell u the back spacing and this is in australia

but they fit my 93 80.. I had to just shave a bit off the rear caliper as u said ..ran it for 8 years like that.. didn't have any trouble..also had 2 friends at the time with the same rims also had no problems..these are 15x8 with 33 bfgs ..i also ran 35inch bfg muds on them..but had a 3inch lift then.

93 & up have the rear disc brakes. There is plenty of threads that go over this subject.
I have read that if you go with steal wheels & 1" spacers you will be fine. Or same as 3.5" back space on the wheel.
I will be doing this vary soon myself. I currently running 1.5" spacers so I forsee no issues on my part.

So you just need steel wheels with 3.5" backspacing? I guess I can't find any how-to's on grinding the caliper either.

Try spending 50 bucks on a steel 3.5" BS rim.
Slide it on very careful so if it doesn't work then you can return it. Then post your findings here.

I look eagerly for you findings and pictures.

Merry Christmas.

Why would you want 15's instead of 16's? My HDJ80 from 92 had 15's standard, but had rear discs. Same caliper as later models I think, just another bracket that puts the caliper closer to the center.

I want to put 80 axles on my 40. The tires I have for my 40 I got off craigs for a killer deal and they are 15s. I got the whole set of tires for 400 bucks. To get 4 of those tires brand new for a set of 4 they cost over 2k. So I would really like to use these tires since I got such a great deal.

Different strokes for different folks.
Use what you got, if it works, run it.
