GM 6L90 Rear Planet (GOOD USED)
The GM 6L90 rear planet fits various heavy-duty Chevy, GMC, and Cadillac vehicles from roughly 2007 through the present, in models like Silverado/Sierra HDs (2500/3500), Express/Savana Vans, Suburban 2500, Tahoe, Yukon HD, Camaro ZL1, and Cadillac CTS-V, featuring its robust design for high-torque applications. Compatibility depends on specific year, engine, and sometimes internal variations, so verifying the part number or specs (like 22-tooth pinions) is crucial for correct fitment across these Chevy, GMC, and Cadillac platforms.
Key Vehicle Applications (Examples):
- Chevrolet: Silverado 2500/3500 HD, Suburban 2500, Tahoe (some), Express Van, Camaro ZL1.
- GMC: Sierra 2500/3500 HD, Yukon HD (some), Savana Van.
- Cadillac: CTS-V, Escalade (some), STS-V, XLR (some).
Years & Models (General Range):
- 2007-2017+: Heavy Duty Trucks (Silverado/Sierra HD).
- 2008-2013: Suburban 2500, Tahoe/Yukon HD.
- 2009-2015: Cadillac CTS-V.
- 2007-Present: Express/Savana Vans (4.8L/6.0L).
Key Considerations:
- Heavy-Duty Focus: The 6L90 is a stronger version of the 6L80, designed for trucks and high-torque performance cars.
- Part Numbers Matter: Always check the specific part number (e.g., 24241350, 24274046) for your vehicle against the replacement part.
- Internal Variations: While the general range is wide, different years and applications (like ZL1 vs. HD truck) can have internal differences, requiring precise part matching.
