OEM GMC P3500 Parts

The GMC P3500 ran from 1979 through 1999. One-ton P-series step van and motorhome chassis. 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.

Body builder configuration affects wiring, frame and brake components on these vehicles. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction.

The parts we move most on the GMC P3500 are front hub assemblies, leaf springs, brake components, steering linkage and fuel system components. On a commercial vehicle 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. Send us your VIN before you order and our parts specialists will confirm the exact part number for your vehicle.

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 Send us the part number off the old piece and we will tell you whether it is still available or what it superseded to. Orders placed by 3pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. The GMC C1500 Pickup is the nearest alternative in the range if you are comparing parts across models.
