Hi all,

I'm just in the process of doing the 14bolt ff swap on my blazer and I'm trying to use my old 36x13.5x15 iroks but I'm not sure about fitment of the wheels and I was wondering how much grinding people have done to do this? Does anyone have a spare 15x10 8lug wheel I can use to try fitment?

Cheers,

Jon

I had 15" rims on a 14 bolt with disks that required the tiniest bit of shaving on the caliper and it was on a meaty point so I felt comfortable doing it. The rim would actually bolt on and spin but you could hear it dragging.

I had the bigger calipers. Forgive my exactness but people make disk kits with both 1/2 and 3/4 ton calipers, I was using the larger 3/4 ton calipers.

Backspacing of the rim matters a lot here too. I'm pretty sure the rims I was running were 4.25". They were definitely 15x10.

I am running a 15in rim on my 14 bolt with drums. Just went with a different back spacing. No grinding.

Just sold my rims on Craigslist, otherwise I'd be able to help ya.

If the wheels have little back spacing (less than 4") they should fit with only a bit of shaving on the calipers, mostly removing casting flaws. Some wheels have a different profile though and fit better/worse. Steel is usually easier than alloy wheels in my experience. The big issue I have seen with wheels with minimal clearance is rocks and stuff will make there way in and grind through, this is especially common when in the mud.
