TH350 to NP229, NP219 and Jeep NP208 Adapter

The Adapter
The Novak TH350 to Jeep New Process transfer cases adapter is very compact at only 1.1-inches long for a combined transmission and adapter length of 22.9-inches.
The adapter itself is machined of a high-grade aluminum alloy, featuring thick flanges and a heavy cross-section.

TH350 Versions
Any version and year of the TH350 can be adapted to the NP transfer cases, from Chevy, to Buick / Olds / Pontiac and Unicase versions of the TH350, as determined by your choice of engine.

Transmission Output Shaft
Every kit comes with a new output shaft for the TH350, whether for 2wd or 4wd transmissions. 2wd versions work equally well as 4wd versions. The Novak output shaft is of an alloy steel, precision splined and hardened for a superior interchange. This shaft connects the TH350 output directly into the existing 23 spline NP / NVG input shaft for the strongest combination.
Advanced computer modeling methods were integral to the design of Novak's adapter assembly. We were able to push the bounds of product and process well beyond the status quo.
Installation requires disassembly of the transmission main assembly, and we recommend the services of a transmission professional. The basic installation is 3-4 hour bench job and may include simple gasket and seal replacements. Some choose this as the time for a more thorough master rebuild and update.

Transfer Case Input Gears
The included Turbo 350 output shaft splines in directly into the OEM Jeep input gears, and transfer case disassembly is not typically required.
