Genuine GM Parts for the Cadillac Commercial Chassis

The Cadillac Commercial Chassis ran from 1980 through 1996. Bare chassis supplied to hearse and limousine builders. 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 Cadillac Commercial Chassis are steering linkage, fuel system components, water pumps, mirror assemblies and headlamp assemblies. 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 Send us the part number off the old piece and we will tell you whether it is still available or what it superseded to.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. If you are working on something else in the lineup, our full Cadillac catalog covers the full catalog.
