GMC shares its platforms with Chevrolet — Sierra with Silverado, Yukon with Tahoe, Terrain with Equinox — but Denali and AT4 trims add their own brakes, suspension, lighting and trim. Many of the GMC parts we quote are for 1999–2013 Sierra, Yukon and Envoy trucks still working every day, so we read the RPO codes off your VIN and match the part to the truck as it was built.
What’s different about GMC drivetrain and exhaust parts
- Front CV axles on 4WD Sierra and Yukon differ between the 1999–2006, 2007–2013 and 2014+ trucks; the rear axle ratio (RPO GU4/GU5/GU6/GT4) sets the ring-and-pinion and is on the glovebox label.
- Sierra and Yukon catalytic converters are engine- and cab-specific — the 4.8/5.3/6.0/6.2 trucks use two converters plus a Y-pipe — and California-emissions trucks (RPO NE1/YF5) need CARB-certified units.
- Driveshaft length changes with cab and bed — regular cab, extended cab, crew cab short and standard bed all differ — and two-piece shafts have a carrier bearing that is a common replacement on long-bed trucks and Yukon XL.
