GM powertrain hardware is built to work for a long time, and a truck totaled in a collision usually has a drivetrain that never took the hit. A 5.3L or 6.2L V8 out of a Sierra, a transfer case from a Yukon, or a six-speed from an Acadia costs a fraction of a dealer crate unit and carries the same factory engineering. Every one is cleaned, inspected, and function-tested before it goes on the shelf.
Configuration is what makes or breaks the order. GMC changed part specs across model years, trims, drivetrains, and cab configurations, and half-tons diverge sharply from 2500HD and 3500HD. Give us the year, model, and VIN and we cross-reference engine displacement, transmission type, and drivetrain setup before pulling anything — so a Sierra 1500 part fits your Sierra 1500, not just any half-ton.
Trim splits, HD versus half-ton, and the badge-engineering question. Need help? Call 1-800-606-1107.
Frequently, yes. Sierra and Silverado share platforms and powertrains across most generations, and so do Yukon and Tahoe. Sheet metal and trim differ; the mechanical hardware often doesn't. We verify the specific part rather than assuming either way, and cross-brand sourcing sometimes gets you a unit faster.
Almost never in the drivetrain. Half-tons and heavy-duty trucks run different frames, axles, brakes, and transmissions. Some cab and interior parts cross over. Send the VIN and we'll tell you definitively.
The eighth character of your VIN identifies it, or check the RPO codes on the glovebox sticker. A Sierra could have a 4.3L V6, a 5.3L V8, or a 6.2L V8 depending on year and trim, with different mounts and transmission pairings for each.
They're unibody crossovers rather than trucks, with FWD and AWD variants and their own transmission families. A 2018 Acadia takes different hardware from a 2015, since the platform changed generations. The VIN sorts it out.
Yes — 1500, 2500, and 3500, including cargo and passenger configurations. Fleet vans stay in service a long time, and donors come through regularly.
Availability is limited but real. Specialty and classic GMCs come through our yards, and demand keeps them moving quickly. Call rather than assuming a part is gone.
Front and rear ratios have to match, so we verify both before shipping an axle assembly or differential. Mismatched ratios will damage the transfer case. The ratio is on the diff tag or in the RPO codes.
If we VIN-matched it and it's wrong, we cover the return and replacement. Every eligible order also carries the 90-day warranty.
