2nd Gen Non-Engine/Transmission 01 alloys wont fit on a 94

[RFyfe]

Well i let my brother have my 2001 2500 alloy rims for his 94 2500 and they dont fit the rear. My truck has rear discs, so i guess thats why they dont fit his or ... ? Is there Anyway to make these fit with out jerry rigging it to bad? This is actually my brothers account.

I think you will have to do some grinding on your 94 drums to get them to fit OR take it to a machine shop and have the rims altered to fit the drumb. Its not a major job.

RFyfe,



I’m running 2001 alloys on my 1997. I took the rear drums to a machine shop and they removed some of the outer lip with a brake lathe so they would fit inside the rims. Before doing this I spoke with Sam Peterson and the machine shop. Both agreed that the material being removed was not structural. Total cost was 1 hour labor. I did not have any clearance problems on the front. Although, we just tried to put the 2001 alloys on Boondock’s 1998 and the rims did not clear the steering linkage. Boondock would need to grind off some material here too.



I would do this mod again in a heart beat. The 2001 alloys allow me to run 295s and keep the tires up under the truck. Backspacing on the alloys is around 6. 5 inches. Most aftermarket rims are around 4. 5 inches.

I ground mine down with a 4" grinder. Pretty slow, about 45 minutes per drum, a 6" er would have been nice. Put one rear at a time on stand, chock truck real good, remove wheel and run about four of the lug nuts back on to hold drum on in perfect alignment. You are going to put truck in low gear, engine running and grind on the material while drum is turning. You need to have the grinder braced on something firm so that it will grind evenly and feed it into the drum against the direction it is turning. If you were to feed it in the direction the drum is turning I imagine it would take your grinder and spit it out the other side and perhaps start all other kinds of havoc. Be careful. I used the removed tire to guide the grinder while I fed it toward the drum.



Be sure to put the lug nuts on as I already mentioned. The drum may be on pretty tight you think, but if it comes lose and gets out of alignment while the truck is in gear it may just lock up against the brake shoes and cause your truck to drive right off your stands. I had that happen one day when I put mine in gear sitting in my truck. Just fooling around, don't recall exactly what my intent was at the time but the truck all of a sudden lurched and I just barely got the brakes before it drove off the stand. The drum was tilted sideways and jammed pretty tight.



Back to grinding the drums. I have about 1/8" clearance around my drums now and could remove even more material. I wish I knew how much space is adequate for cooling and how the hot drum is affecting my tires. It seems to be fine as is. I got the brakes pretty hot one day and felt the rim on the inside and it was only warm but the real test would be going down a long grade or doing it repeatedly in some kind of situation. Dunno.



The improvement in my truck is wonderful. I drove it for ten years with the factory rims not knowing just how out of round they were. The truck now runs smooth and handles better. One extra I did that made part of the difference. I had the tires balanced on a Hunter Road Force balancer. Some say this is not a cure all but it did remove a small amount of jiggle that I was still feeling after putting on the new michelins and having them balanced on the standandard balancers. My truck rides silky smooth like I have never seen before.



Be sure to keep the grinding dust away from painted surfaces, it will attack the paint and make you very unhappy.



If you have a machine shop and money go there.

I just tried to fit some 01's on my 91... rear fit good, couldn't even get them on the front. . kept hitting the dang brake caliper... maybe it'll stop OK with just the rear drums... hmmm...

I put '01 alloys on my '98. All I had to do was have the rear drums turned. I had no clarence issues up front. My cousin did the same only his is a '97 and he had to do a little grinding on the steering arms up front but not much. I think it all depends on how the parts are cast and machined up there. My front axle is a '96 so should be about the same as the '97 but still mine fit and his didn't.
