Frame, brakes, axles? Engines and transmissions are the same across the board, so what's different?

Does the 3500 come standard with 4.10?

I would assume that the spring rates different at least in the rear. I don't know much about the torsion bars in the front of a 4wd but i would assume they would be heavier as well.

What is the gvwr for the trucks. If they both are 8600 GVW then they are most likely the same all things being equal. The 2500/3500 trucks can be had with most of the gear sets that GM offered. The front torsion bars are the same basic spring the spring rate is what changes.

8600vs 9200 GVWR for SRW trucks. Rear end gets an upper overload that the 2500 doesn't and 1 ton has larger transfer case. AFAIK the rest is the same.

Another thing that we need to know is the year of the truck. The 4.3 was the base engine in a 3500 in 1988. The early trucks did not have a 9200 GVW and the rear differential could be Semi or full float.

I have often wondered this myself. I have a 2000 K3500 reg. cab 5spd I bought about 8 years ago (this truck is a beast and I love it!) and about a month ago I bought a 99' K2500 CCSB auto. Both have the 7.4. Just by looking underneath I can tell the drive shafts and rear axles are different but the front suspension and rear leaf springs look the exact same. I am also curious what the difference is between the SRW and DRW?

Driveshafts are gonna be different, I'm betting the CC had a carrier bearing. DRW axle was a different width but used the same leaf pack as SRW.
