OEM GMC Suburban R1500 Parts

Limited availability on pre-2010 parts. Factory parts for vehicles older than 2010 are getting harder to source every year. We can still get many of them through GM remaining stock and vintage parts channels, but supply is limited and availability changes without notice. If your part shows in the catalog, order it and we will confirm availability right away, or contact us first and we will check before you buy.

The GMC Suburban R1500 ran from 1987 through 1991. Two-wheel-drive Suburban under the R-series naming. 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.

Wheelbase and rear suspension design separate these SUVs into groups that look identical from the outside. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed.

The parts we move most on the GMC Suburban R1500 are third row seat components, headlamp and taillamp assemblies, mirror assemblies, water pumps and transfer case components. On a full-size SUV 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. Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back.

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 Send us the part number off the old piece and we will tell you whether it is still available or what it superseded to. We ship from Dallas, and in stock orders placed by 3pm Central usually go out the same business day. If you are working on something else in the lineup, our full GMC catalog covers the full catalog.
