Browse our inventory of used OEM Cadillac parts sourced from US-based salvage facilities. Every component is a genuine factory-original part inspected for condition and listed with full vehicle compatibility details. Cadillac's GM platform sharing — particularly the Escalade's identity with the Chevrolet Tahoe/Suburban and GMC Yukon — means the much larger combined GM donor pool is fully accessible for many Cadillac structural and drivetrain components. Free shipping on all US orders. VIN fitment confirmed before dispatch.
New OEM Cadillac parts carry a significant luxury brand premium. Used OEM from low-mileage accident-damaged donors delivers the same factory engineering at 50–65% less — and for platforms like the Escalade, which shares its entire body-on-frame architecture with the Chevrolet Tahoe, Suburban, and GMC Yukon, the combined GM donor pool provides outstanding availability at competitive pricing that Cadillac-only sourcing cannot match.
Cadillac Models & GM Platform Cross-Reference
| Cadillac Model |
GM Platform Twin |
Key Cross-References & Notes |
| Cadillac Escalade / ESV / EXT |
Chevrolet Tahoe / Suburban / GMC Yukon (GMT800/GMT900) |
Transfer cases (NP246/NP263), rear differential carriers, intake manifolds (5.3L/6.0L/6.2L V8), factory navigation radio (AM/FM/Nav/SAT/DVD), ABS pump — all cross-reference directly across the full GMT family. Escalade ESV cross-references with Suburban, Escalade EXT with Avalanche |
| Cadillac CTS / CTS-V |
Cadillac Sigma / Alpha platform (rear-wheel drive) |
Cadillac-specific rear-wheel-drive platform. Front differential carrier (3.23 ratio, AWD variants) available. CTS-V uses supercharged LSA/LT4 engine — confirm trim before ordering any engine component |
| Cadillac STS |
Cadillac Sigma platform (shared with CTS) |
Sigma platform shared with CTS — some structural and drivetrain cross-references apply between CTS and STS within the same generation |
| Cadillac SRX (1st gen) |
Cadillac Sigma platform (RWD-based) |
First-generation SRX (2004–2009) uses the Sigma rear-wheel-drive platform — distinct from the second-generation which moved to a FWD-based crossover platform |
| Cadillac SRX (2nd gen) |
GM Theta platform — Chevrolet Equinox, GMC Terrain (partial) |
Second-generation SRX (2010–2016) uses a FWD-based platform with AWD — transfer case and front subframe cross-references available with Equinox/Terrain of the same era |
| Cadillac ATS / CT4 |
Cadillac Alpha / Alpha2 platform (rear-wheel drive) |
Cadillac-specific compact rear-wheel-drive platform. Front differential carrier available for AWD variants. Always confirm RWD vs. AWD before ordering any drivetrain component |
| Cadillac CT5 |
Cadillac Alpha2 platform |
Shares Alpha2 architecture with CT4 — rear-wheel drive with available AWD. Cadillac-specific components with limited external cross-references |
| Cadillac XT4 |
GM VSS-F platform — Chevrolet Equinox (2018+) |
XT4 shares its compact crossover platform with the third-generation Equinox — structural and AWD drivetrain components cross-reference within the same production year |
| Cadillac XT5 / XT6 |
GM C1XX platform — GMC Acadia (2nd gen) |
XT5 and XT6 share the C1XX platform with the second-generation GMC Acadia — subframe, transfer case, and front differential cross-references apply |
| Cadillac DeVille / DTS |
GM H-body — Buick LeSabre / Park Avenue, Oldsmobile Aurora |
Front subframe and suspension components cross-reference across the H-body family. The combined Buick LeSabre and Park Avenue donor pool provides better availability than DeVille-only sourcing |
Escalade — Largest Part Category in Our Cadillac Collection
The Cadillac Escalade is our strongest Cadillac inventory category — and for good reason. The Escalade shares its GMT800 and GMT900 body-on-frame architecture completely with the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and GMC Yukon XL. Every transfer case, differential carrier, intake manifold, ABS pump, and structural component is interchangeable across all four nameplates within the same production year range.
The Escalade ESV (extended wheelbase) cross-references with the Chevrolet Suburban and GMC Yukon XL. The Escalade EXT (pickup configuration) cross-references with the Chevrolet Avalanche. This means the Escalade effectively has one of the largest combined GM truck platform donor pools of any Cadillac model — delivering outstanding parts availability at pricing that reflects the much larger combined fleet.
🔧 Escalade = Tahoe / Suburban / Yukon for Parts
If the specific Escalade component you need isn't listed, search our Chevrolet or GMC inventory for the Tahoe, Suburban, or Yukon equivalent from the same year — it's a direct fit. The Escalade premium is a badge premium; the engineering is shared completely with its Chevrolet and GMC siblings.
