chevy 2002 1500HD Silverado

No, what I said was... the 1500HD was not a true 2500HD. The 1500HD depending on model year was also sold as a 2500. Not a 2500HD. Big difference. 1500HD/2500 got semi floating axle, lighter springs, less tires and wheels, all on the 1500 frame. The 2500HD got FULL floating rear axle, beafier springs, tires, and wheels all on a heavier frame. I believe the 2500HD also got bigger brakes, but that can be verified by checking a parts manual. The 1500HD was there to bypass some licensing laws for some states. Allowing them to be licensed with passanger car plates instead of truck plates due to the lower GVWR that GM placed on them. They were never a big seller as those that needed to tow heavy bought the 2500HD, those that wanted a passanger car bought the regular 1500.
