Will wheels from 2014-2015 2500HD fit on 3/4 ton GMT800?

calsdad · April 5, 2015

I thinking of doing an overall upgrade to my 2003 Chevy Suburban 2500.

I'd like to possibly add bigger brakes to it - and I just sort of like the look of some of the wheels that are coming on the 2014 & 2015 2500HD Silverados.

Does anybody know if the later year wheels can be swapped onto a GMT800 2500 series 8 lug truck?

I thought I remember reading in one of the truck forums (can't remember which one) - that the wheels are not a direct interchange and a spacer is needed or something like that.

With the 2011 redesign came a new lug pattern (8 x 180mm). Until then, all HD trucks used a standard 8 x 6.5" pattern since the dawn of time. As you said, you can get a lug pattern adapter and run the new ones if you'd like.

There are, however, a host of good looking stock wheels that will bolt directly to your rig (H2 wheels with your current center caps, 3rd gen Dodge 5 spokes, again with your current center caps etc.).

Bloody hell. Thanks GM - always finding a way to make things harder.

I'm wondering about the 20inch wheels because I'm contemplating a total resto / re-do of my 2003 3/4 ton Suburban. I'd like to upgrade the brakes - and I'm thinking about going with a Wilwood setup which if I remember correctly said it needs a 20" wheel for clearance. Plus I just like the looks of the Chevy 5 spoke.

So if the 2011 redesign went to the new bolt lug pattern - and my understanding is that the frame from the GMT900 and GMT800 Suburbans is the same - then I could use the new wheels if I sourced out a 2011 and up GMT900 11.5" rear axle - and some 2011 and up GMT900 hubs - which should have the correct "new " lug pattern for the new wheels?

If that's the route I need to go - it's not that big a problem - because if I pursue this project - I'd be swapping in an 11.5" axle anyway. And I'd be rebuilding the front suspension - so putting in the correct hubs isn't that big of a problem.

And you can keep your rear axle, you would just need the correct shafts.

You can get adapters to fit the new bolt pattern they make factory reps of the 20's in that bolt pattern, I have seen them before

I was thinking that might be true - but if I'm going to do this rebuild - I was planning on going to a 11.5" axle (the truck currently has the 10.5"). It's my understanding that the rear spring pads for the 2500 chassis on the GMT800 and GMT900's - are all the same spacing. So I'm thinking I should be able to get an 11.5" axle that is just a bolt in - and I either need to get an complete axle assembly from a 2011 and up GMT900 3/4 ton - or if all I can find is an earlier year with the old spacing - just do like you said and swap out the axle shafts to ones with the new bolt pattern.

That actually sounds like the easy part.

I just need to figure out if the front hub/bearing assembly for the 2011 and up GMT900 will be a drop in. I don't know how much parts interchangeability there is between the GMT800 and the GMT900 chassis.

That's one of the reasons I'm thinking of using the factory 20" wheels - them seem to be readily available on places like Ebay and Craigslist - plus I just like the way they look.

Edit: Doh! - I should have read the auction a little more closely - I didn't realize those were new style wheels in the old bolt pattern.

Replicas are good wheels. I have had Replica SS wheels for 4 years and 90k on them. Saves you some work

Chris · April 6, 2015

Here is a great company with replicas. They have more than just chrome of the wheels you want. There is black and also machined. They also have both bolt patterns so whichever way you do decide to go

Awesome - Thanks!. That's one item off my investigation checklist to help me decide if I want to pursue this project or not. My Suburban is about the same dark grey color as your GMC - and the wheels you've got on it look good - I think they'd look good on my Suburban too.

But my wheels ate only 6 lug. Options for a stock looking 20" in 8 lug are slim unfortunately

That website you pointed me to has a number of GM replica 5 spoke options for the 8 lug wheels - including one in the "old" bolt circle diameter.

They must be the same wheels - and they're cheaper at the place you posted than the Ebay auction that was posted earlier. I'm just happy there's a relatively easy option to get what I want. Plus the cost is not bad - it's cheaper than a lot of non OEM wheels out there.
