Okay, I've read in the sticky and other posts but haven't really read much on fitting 2nd gen dually rims on a first gen. I'm want to install these rims on this truck and wandering if it will work. And not these particular rims I'll still need to find a set. Or more headache than its worth?

I seen them on other fist gen bolt patterns shouldent be different find a friend that has a spare and see if it fits

The "experts" will start telling you about lug-centric vs. hub-centric differences in wheels, but I have run 2nd gen inners and aftermarket outers (and fronts) for 15 yrs with no issues. The bolt holes may need some slight enlarging depending on the particular wheel (5/8 vs 9/16 stud size), but the most I have needed to drill was 1/16. My machinist said I could do this at home, and I did w/no ill effects.

dodgenstein has it right I have also been running 2nd gen wheels for many years now. Had to drill the holes just a little bit.
I use my 2nd gen wheels for my drag tires..

I put the third gen wheels on my truck and all I did was drill out the holes with a step bit on either side of the rim, since the third gens have 9/16" studs and our dually's have 5/8" studs. No weird vibrations came up or anything of that nature. The Only thing was I wasn't able to use the center cap that came with the simulators so I just use my stock caps. Wheels look good though!!

Isnt the offset different on 2nd gens?
Guys if this is the case would it be possible to use 16" Alcoa's for 2nd gens? Does the 2nd gen wheel have the little hole in them where are little pilot hole goes? Has anyone ever done that? Sorry for hyjacking the thread but I want alcoa's badly on mine.

TLRMAN, your truck looks awesome!

2nd gen mag wheels are different story... I hate trying to explain it but it involves spacer platers on the rear and 16 additional lug nut to tighten.

Cool, it sounds like it will work pretty easily now I need to find someone that has a set laying in the garage after their 24.5 swap. lol But also I found a set of the 16" Alcoa rims that are on one of those late 70's front wheel drive GMC motor homes which I think have the Chevy 1 ton pattern. they are held on by the the same style lug nuts as my D-350. but probably 9/16 studs. I've about talked this cat out of the Alcoa's and theirs six rims instead of 4 so I'll probably have to replace the rear studs for longer ones to accommodate for the thicker aluminum rims. I would rather have the Alcoa's.

Hey TLRMAN those rock stars make that truck look evil. Love it.

deanhinsley1963 Thats scary. I had the same cattle pusher on the front of mine When I found it.

My pin is missing on one side. I think its there more as a fool proof way to make sure your coins are in the correct position. Of course you know already all you have to do is look before the wheel goes on the hub to make sure it nest's correctly.

After talking to many people with 1st gens with aftermarket rims on their dually's I've come to the consensus that the coined type are what they are DESIGNED for, but the others still work. Use some coned lugs to center the rim to the hub all the way around and your good to go as far as I'm concerned.

Thanks guys for the info. I guess Alcoa's are out of the question then. RAM

Alcoas can be used, I got a set at a swap meet that came off a chevy. Front and outer rear aluminum, steel inners. The front fit fine, but the center holes had to be enlarged in the rear to fit over the hub, but I've had them on my 93 w350 for 3500 miles with no problems.

Sweet, I'm on it. I'll see if I can cabbage those Alcoa's up this week. I'm with freight train. I like those better too. I think it makes the trucks look more like a little rig.
