Our TH350 to Dana Models 18 & 20 conversion helps makes for a strong and capable powertrain, both on-road and off-road. It is one of the most persistently popular transmission conversions into Jeeps, providing a compact geartrain, compatibility with excellent engines, and ease of installation.
The Novak TH350 to Jeep Dana 18 & 20 transfer case adapter is compact at 2.9" long, for a combined transmission and adapter length of 24.6". This short length allows fitting in even short wheelbase Jeeps. The adapter itself is cast and machined of a high-grade aluminum alloy, featuring thick flanges, a heavy cross-section, and strength-adding gussets. The adapter shaft is machined from triple-alloy gear steel and provides superior strength as it is carried by two bearings unlike the other single bearing versions on the market. The Dana 18/20 input gear is rigidly supported by this configuration to handle gear side loads.
Kit Contents
The 103 Kit includes adapter housing, adapter shaft, bearings, seals, correct locator for your transfer case model bore, steel mount foot, hardware, and instructions. These parts will come assembled to the extent possible.
