Rear wheels are sucked in way more than front. K10. Adapters? BAD IDEA? pics inside

The '88-'98 style trucks with the newer style body.

Correct - it's the internal program code.

It went GMT400, then GMT800, then GMT900, then K2 (maybe) and then I don't remember - seems like there was a "T1" in there somewhere.

What might not be obvious is you can then build additional information into the program code, like GMT820 = short utility, GMT830 = long utility. GMT820C = Cadillac, GMT830D = Denali. GMT805 = Avalanche etc.

I've been using these wheel spacers for the last two years with no issues. For the first 6 months i would periodically retorque the lugs and found no changes.
My real concern was they would loosen, but that fear is gone now. And i love how the rear wheels fit now.

so if the first gen Chevy Colorado is GMT 355 and the Avalanche is a GMT 805, does that make the chevy avacado a GMT 450 (the difference between 805 and 355) or does it make it a GMT 1160(the sum of those two)?

Either your bump stop for your rear leaf is missing or its a small tiny one lol

I'm sure that Doppleganger is on to something here. It's not a GM-specific thing. Jeeps had narrower rear axles than the fronts, as well. For example, wide-track CJs ('80s-era) had front axles that were about 2" wider than the rear (56.5" front, 54.5" rear).

Craig

Scouts had a narrower rear track as well, and the travelall as well. Seems pretty common in the 70s on vehicles with front leaf springs, especially when the 40* steer axles came out. There had to be enough clearance for full steer without hitting the springs.
Might have been easier for the lighter Ford's since they had coils, still had to worry about radius arms
Still don't know exactly why rears are usually narrow.

Doesn't matter. The avalanche is the ugliest vehicle GM ever produced! This avocado thing is just as hideous....just in a smaller portion.

The Avalanche is one of the best designs to ever come out of GM. I wish they still made them. Actually, they do, if you want an electric truck. But of you think the Avalanche is the worst thing GM ever did you've obviously never seen an Aztek.

Hmmm, your right. How have i been looking right past that this hole time...new one's on the way lol

It was great when they started offering them without the cladding... but that option was not available on the 2500, which is the one that interested me. If you could have got a 2500 without cladding, I literally would have bought a new one, no doubt about it. I was really close to saying fock it and get one with cladding, but just couldn't do it.

I just called Walter and told him of the blasphemy you blathered. He wasn’t happy.

Truth! Aztec easily in top 10 fugliest vehicles ever.
The plastic cladded Avys were ugly imo. But once they ditched the plastic they were fine.
The convenience of a removable rear window and bulkhead was never of any use to me and never will be. Although it was innovative and seems still popular as nice Avys fetch as much $ as CC pickups. Ida guessed 10-15 years ago, no one would want them by now and they’d be dirt cheap.

The plastic cladding never bothered me, but you could order them with it deleted.

As far as the window and the mid-gate, it was far more useful for most people. Pickup trucks are fairly impractical vehicles unless you're hauling cargo frequently. So, the ability to have a five-passenger cabin that could still be converted to carry 8ft cargo for the few times most of us need a truck was a game changer. Particularly since you didn't have to deal with a mile-long vehicle like a crew-cab.

It's also WAY more useful than these half-@$$ed half-bed four-door things they call pickup trucks today. I'm really surprised that people didn't embrace the Avalanche far more than these overgrown sedans with a divorced trunk. Honestly, I don't think a lot of people knew about or understood the mid-gate. I had a few people talk about how useless the short bed was that were totally clueless that you could get 8 feet of plywood in it. Too bad. I still think it was one of the most innovative ideas any auto manufacturer ever had.
