BD Diesel Built-It Trans Kit 2006-2007 Chevy LBZ 6spd Allison Stage 4 Master Rebuild Kit

If you're looking to rebuild your own Allison 6-speed transmission, especially for a 2006-2010 Chevy Silverado or GMC Sierra with the LBZ or LMM engine, this Stage 4 Master Rebuild Kit from BD Diesel gives you the core components used in their own performance builds. This kit includes all the basic rebuild parts and gaskets you'll need, plus upgraded clutch packs and machined components designed for increased durability and performance.

Inside this kit, you'll find Raybestos Z-Pack clutch packs for both the C1 and C2 applications, known for their strong performance. BD Diesel also includes their own machined parts, such as the C3, C4, and C5 plate assemblies, along with a BD-machined C3/C4 piston. These components are crucial for handling higher power levels and ensuring consistent operation. You also get a deep suction filter and a main filter to keep your transmission fluid clean, a pressure switch assembly, and a shift kit to help fine-tune the transmission's behavior.

This kit is designed for the seasoned builder who wants to put together a robust transmission rebuild. BD Diesel backs this kit with a 12-month or 12,000-mile warranty. For a complete rebuild, consider pairing this kit with a BD Heavy Duty Transmission Pan, sold separately, to further enhance your transmission's cooling and capacity.
