Product & Features
The Adapter
The Novak 4L80 to Jeep transfer cases adapter is compact at only 3.0″ long for a combined transmission and adapter length of 29-1/4″ (equivalent to a ~22-5/8″ manual transmission). The adapter itself is machined of a 6061 billet aluminum alloy, featuring thick flanges and a heavy cross-section.
Transfer Case Clocking & Rotation Options
Our adapter is drilled for multiple clocking locations from near-factory (20 degrees down) to near-flat (3 degrees down). However, pan clearances and front axle width may inhibit the flatter options.
Rear Mount Provision
This transfer case adapter’s design features a modular mounting and support system and mounting base, ready to accept our industry standard urethane isolator mount, available for purchase below.
