If you can get ahold of the center caps for the OBS trucks, those look way better on PY0s than the ones they came with.
This is the cap I'm talking about; Silverado got the chrome ones and Cheyenne and Scottsdale got the same cap in black plastic. The black plastic lug nut covers work with either cap, as long as you have the factory lug nuts with the threads on top.
I haven't actually done it (since I don't have the alloy wheels yet) but I've seen many trucks on gmt400.com that have the 400 cap on the 800 wheels, and I swear I've seen some on here too. Been told on gmt400.com that it's doable. The plastic nut covers and lug nuts that they go on, are used on both series' trucks. There are also SAE thread lug nuts that are made with the threads on the top for the plastic covers; I had a bag of them but they're mislaid in the shop. I know they are SAE and not the 14mm that my crew cab and Burb use, because I tried them on the trucks and they were the wrong threads.What's the secret to doing this? I once tried running the older caps on my yellow van and from what I remember, the plastic lug caps didn't have enough thread engagement for it to hold on well.

That may be one of my aversions to them. But never liked the look at all. One of GMs poor decisions in wheels. Who tf is using 16x6 wheels on their flagship HD trucks all the way into the 2010s? Was like a slap in the face penalty for all Duramax buyers for the first 10 years. Spend big bucks on our truck and still have to get wheels to run bigger/wider or heavier duty tires…Agreed. They are even repopped too, I just wish they were offered in 8" wide. It seems silly to reproduce them, but not offer other sizes.
even though I missed the aluminum part at first, you’re asking for something that is not produced fairly certain.This is what I am looking for in aluminum.
They are not made in aluminum. The rally wheels were steel, painted silver with a stainless trim ring and chrome center caps. Anything aluminum would not have the trim ring.This is what I am looking for in aluminum.
