OEM GMC C3500HD Parts

The GMC C3500HD ran from 1991 through 2002. Heavy duty one-ton chassis cab with a wider frame. Because that run covers more than one engineering generation in most cases, the single most important thing you can do before ordering is confirm which year you are working on. Parts that look interchangeable across a nameplate very often are not.

GVWR rating, wheelbase and upfit body all change part numbers on commercial chassis. Everything on this page is a factory GM part, built to the original specification and carrying the original part number.

The parts we move most on the GMC C3500HD are cab mounts, mirror assemblies, front hub assemblies, leaf springs and brake components. On a commercial chassis these are the components where the difference between a factory part and a discount replacement shows up fastest, because they carry load, heat or both. If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out.

On a vehicle this age, availability is the real question. Mechanical and driveline parts are often still active under a current GM number, while model specific trim, sheet metal and lighting may be discontinued. Send us the part number off the old piece and we will tell you whether it is still available or what it superseded to. In stock orders placed by 3pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. If you are working on something else in the lineup, our full GMC catalog covers the full catalog.
