This is great information, I was just typing up a new thread on this exact question so really appreciate you posting the parts numbers. Couple questions for you:

You ended up going with 3/8" spacers, correct?

What brand spacers did you buy?

They were hub centric, correct?

Did you also buy aftermarket lug nuts?

Appreciate your help on this!

1. I used 3/8" spacers on the front and "1(one)" 1/2" spacer on the driver rear (long story). There is enough thread to use 3/8" or 1/2" spacers.

2. I bought Bora brand spacers - aluminum. They make aluminum and steel spacers. Wheel Adapters, Wheel Spacers, Hub Rings for your car! | Motorsport Tech (motorsport-tech.com)

3. Yes, hub centric.

4. I used my factory lug nuts (same thread size and pitch).

Please do tell, this has got to be interesting.

Like most new Silverado 1500's, my rear axle is offset to the passenger side by 1/2". So, instead of trying to figure out how to shift the axle 1/4" towards the driver side, I just decide to add a 1/2" spacer to the driver side. Now both wheels sit evenly in the rear wheel wells.

Just finished this upgrade to accommodate 1/2 in spacers due to a set of methods I purchased that would hit the caliper in the front, very happy with the results, you only need to remove the dust cover in the back without touching the calipers and I made a hole on the dust shield in front which saved me from removing the axles and hubs.

Yep, that's the other way it could be done that I forgot to mention. I just didn't want to drill holes in my dust shields, so I took the long way.

Followed the guidance from the op and had this done in my driveway with hand tools in about three hours. I used 1/2 inch spacers.
Thanks!

I'm about to install the ReadyLift 2" kit on my Trail Boss. Readylift said I needed 1/4"-1/2" spacers to run 285/75r18 tires on my OE wheels, so I bought 1/2" spacers. Thanks for this info. I will be doing this as well.

Thanks for all the valuable information on this thread. I'm getting ready to do this myself. Does anyone know why the Dorman rear studs are twice as expensive as the front studs? Also, has anyone considered just buying new front studs and moving the old front studs to the rear? It looks like the old front studs are 71mm in length which would be sufficient for the rear.

It's an option. But the Dorman studs are 1/2" longer than the stock rears, and the GM stock front studs are only 3/8" longer than the rears. Also, the Dorman has more threads than the stock front as the threads go almost all the way to the end of the stud.

Why is the axel shifted to the passenger side 1/2"?

I don't know why, but that's the way they come from the factory. Well, most of them.

Can anyone who ran 1/2 spacers post pics of the "poke"? I just lifted my elevation with an Eibach pro truck kit and needed UCA. I now rub on the arm of the UCA and the 1/4 spacer didnt do the trick. I do not care for "poke" out so I want to get by with the thinnest spacer that clears the UCA rubbing I'm getting. Thank you

Why don't you take your 1/4" spacers and double them up on one side to see how it looks?
