I think I can civilize the ride of our C2500 Suburban by swapping in a regular/non-HD C1500 suspension for more labor than money. From my research, the major parts that are different include the front upper control arms, front coil springs, front spindles, front calipers and rotors (with ABS reluctors), 10-bolt rear axle for 5-lug wheels and 4 leaf rear springs (3 leaf springs were available on base trucks). And a set of 5-lug wheels, of course.

From what little information is out there by folks who did the 1/2 ton to 3/4 ton upgrade, it's all plug-and-play.

Unknowns include:

- will the prop shaft bolt up to the 10-bolt axle?
- can I find a ~3.40 diff (everything's 3.73 around here) to drop engine revs with smaller wheels?

What else am I missing?

Finding a 95-99 2WD Diesel 'burb with fabric upholstered seating for 9 was a stroke of luck. I've never seen a Diesel with mortal suspension. I don't want to have to get the local smog Nazis approval for an engine swap.

No towing or heavy hauling duty for this 'burb.
