Advance Adapters Transmission & Drivetrain Parts

Swapping around engines and transmissions is easier with tough, dependable components from Advance Adapters. The company started in 1971 with a single adapter, mating a Muncie car 4-speed to a Jeep Dana 18 transfer case. Today, that selection has grown to keep pace with the popularity of off-roading and rock crawling, with parts like the NP231 SYE (slip yoke eliminator), adapter bellhousings, conversion clutches, and output shafts. Advance Adapters engineers motor mount kits and headers to support a wide variety of popular engine swaps, plus components like oils pans, radiators, and filter relocation kits to finish your swap. Summit Racing carries trail-tested Advance Adapters products, like low-gear transfer cases, twin-stick shifters, and Jeep crossmembers and adapters.
