Help with 2500 Hd wheels

May be the difference from a full floating Eaton and a Dana 60?

Perhaps I should simplify things further. The caps will not fit into the wheel properly even if I don't have them mounted on the truck. I am thinking there must be another cap available.

I can't speak for why your caps won't fit off the truck, but like everyone else said, it is because you have a Dana 60 rear, right?
My truck below had a factory Dana 60 rear and the center caps would not fit. The FF hub sticks out further on the 60 than on the Eaton. I swapped a late model 14 bolt in mine and everything went together.
Hope this helps.
And those center caps aren't held on too secure with those cheap plastic lug nuts in my opinion!

Barnfind- Nice truck!!! I like it!!!

I do have the Dana 60.

That's the reason the caps won't fit depth wise, you have a Dana 60.
I suspect that the reason the dually caps won't fit, is because the dually wheels are entirely different and must have a greater dish around the lug nuts.

Your truck appears to also be factory rear leaf springs, just like mine.
What is yours geared? Mine was 4.56, and that is the reason for the 14 bolt swap. To get some more highway friendly gearing.
FYI and you may already know this. A late model (73-up) 14 bolt is almost a direct bolt in. You just have to move one shock mount and get longer e-brake cables.

I really like your truck, I'm kinda partial to the 3/4 tons! HAHA!!!
Got any pics of the whole truck?

I know that's why the caps wont fit. I researched this all over this board before I had the wheels powder coated. I learned that I needed the taller caps to clear the Dana 60 rear end. That is why I have the taller caps. It just seems like something must be different with my set up because other guys make no mention of having issues getting the caps to fit the wheels properly (not referring to the axle clearance now). The only way I see this working out is if I space out the rear wheels far enough to use the shallow caps or I cut part of the base off of the tall caps.

Does anyone know if GM caps are different between the steel and aluminum wheels on a dually?

My truck has factory coils. I am in the process of putting in a 700r4 transmission. Hopefully I don't have to change rear ends after the trans is done.


I will post some pictures later.

I think I have a set of the deep caps at the shop that are different than yours.
I will look and see and see if they will mount up. Maybe an option for you.

Wow, a coil spring Dana truck. I believe those are quite uncommon. I had a 68 coil spring 3/4 truck many years ago. it was an Eaton rear, but I swapped a 14 bolt in it too. A little more involved than on a leaf spring truck, but still easily doable. I drove that truck for many years, and it sure did ride better than my leaf spring I have now.

I believe there are 2 different caps, ones for the steel wheels and ones for the aluminum wheels. Only a slight difference where they fit to the wheel. I bet you have a set for the steel wheels. Check that out and see.

This is 100% true. I went thru this when swapping from gmc caps to Chevy caps on my brother in laws 06 2500hd. We got a cheap set of OE Chevy caps from Craigslist and fought and fought with them. I finally got to comparing part numbers and there are 2 indeed different caps. I'm sure a belt sander would probably fix the issue pretty easy.
