Asked by tom from baltimore md on

Tom As far as the drive shafts you should plan on replacing them depending on type of original transmission and amount of lift length shafts will change. The length of the new transmission is 27" from face of bell housing to end of transfer case mount. compare this to your existing transmission. now would be a great time to install a short shaft kit in your transfer case http://jo.my/231kit be sure to get an quality external trans cooler to protect your transmission http://jo.my/m8ryn Thank You

Manufacturer

Advance Adapters got its start in Downey, California in 1971 with a single adapter mating a Muncie car 4-speed to a Jeep Dana 18 transfer case. Eventually headers, overdrives, motor mounts and linkage brackets were added to the offerings to complement their core adapter components. When interest in rock crawling spiked in the mid-1990s, Advance Adapters offered low ratio transmission swaps then switched gears into the ultra-low gear transfer case arena. Today, the company is based in Paso Robles, California and their engine and transmission conversions for Jeeps are in kit form and sold as individual components. Shop Advance Adapters Now
