factory aluminum wheel
I would appreciate any info on the factory aluminum wheels that were an option on our trucks. The ones in question I believe have 8 holes and accept the same center caps that the rally wheels do. I would also appreciate the rpo code.

Re: factory aluminum wheel
Off a 91 I parted a few years ago, is the best help I can offer quickly.

Re: factory aluminum wheel
Those are the factory RPO PH7 Forged aluminum wheels.
They were also available in later years as an RPO N90, which was the same (appearance) wheel but changed to a cast wheel as a cost savings. They were available on 1/2 ton 2wd (5 hole 5" bolt circle) and 1/2 ton 4wd (6 hole bolt circle). K

Re: factory aluminum wheel
One last thing, how do you tell if they are forged or cast?

Re: factory aluminum wheel
By looking at the back side. Cast has real "fine" (ie, narrow) parting lines; forged has wider parting lines where the tooling comes together to form the wheel.
You probably won't be able to tell unless you have one of each laying side by side. K
