1976-79 CJ QUADRA TRAC TRANSFER CASE
The Jeep QuadraTrac represented a number of firsts for Jeep and the 4wd industry. As had been the case since 1941, Jeep was driving the entire industry’s transfer case technology at the leading edge. The QuadraTrac was the first transfer case supplied by Borg-Warner in a Jeep (all previous versions were Dana or New Process models). It was the first chain-drive transfer case to enter mainstream truck use and it was the first to have an aluminum case. It was released in the 1973 Jeep FSJ Wagoneer.
- 1973 to 1979 SJ Wagoneer & Cherokee
- 1976 to 1979 Jeep CJ7
This unique transfer case had an integrated limited-slip differential much like an axle, that transfers power to the front and rear axles. A driver operated vacuum switch (usually located in the glove compartment) allows this differential to be locked at will.
The QuadraTrac has an aluminum case that splits laterally around its perimeter. Both front and rear output yokes are offset to the passenger side. The unit may feature a planetary reduction gearbox (as pictured, above) that is inline with the transmission output shaft.
