Our GM 700R-4 adapter to the Jeep Borg Warner Quadra-Trac transfer case is 1.00" in length. The overall length of the new combination is identical to the TH400 assembly that is being replaced. Our kit will include a adapter plate, spud shaft, bearing, snap ring, gasket, o-ring, fastening hardware, and adapter instructions. The original Quadra-Trac 4wd adapter housing must be retained.
The adapter assembly fits the Jeep BW-1339. This is the original Jeep Quadra-Trac. This Borg Warner transfer case was introduced into the Wagoneers and trucks for the 1973 model year and lasted through the 1979 model year. It found it's way into the CJ-7 line from 1976-79 as an option. It features an aluminum case, chain driven, full-time 4wd with a right-offset rear output.
This kit is designed for exclusive use with the 4wd 700R-4 / 4L60 / 4L60E manufactured thru 1996. The overall case length of the transmission is 23.375", has a non-removable bell housing, and a 4 bolt square rear case. Late model 4L60E automatics will have a removable bell housing and a 6 bolt hex pattern rear case. The late model automatic will require an additional Advance Adapter to work with this kit.
