The Dodge NV4500 adapter to the Land Cruiser 19 spline transfer case is 6.375" in length. And the overall length of the transmission and adapter is 18.750". Adapter material is 356 T6 heat treated aluminum alloy. The adapter has a provision for our heavy duty transmission mount. The adapter kit includes adapter housing, 19 spline spud shaft w/ 23 spline internal, shift bracket, sealed bearing, set collar, gasket, nylon nut, fastening hardware, and adapter instructions.
This adapter assembly fits August 1980 to 1989 transfer cases. The transfer case design was changed to a split-case design configuration with a 19 tooth internal spline on the input gear.
Dodge 4WD NV4500 (1993-2000): This transmission is the same as the 1996-99 Chevy version; however, the only difference is the transmission input shaft which is 7-1/2" long with a pilot tip of .750". The output shaft on this transmission is 23 spline. To couple to this output shaft, you will be required to shorten the stickout length to avoid pre-loading the bearings in the transmission.
Dodge 4WD NV4500 (2001-2006): This transmission is the same as the 1993-00 Dodge version; however, The 2001 & newer Dodge transmission was changed to a 29 spline output shaft.
Dodge 4WD Heavy-Duty (Diesel) NV4500 (1993-2006): This transmission is normally used up to the Cummins Diesel. This transmission is similar to the standard duty version in reference to the bolt pattern. The input shaft is the same (7-1/2" long & .750" pilot tip), but the clutch spline is 1-1/4" 10 spline. The output shaft on this transmission is also larger in diameter, which has 29 splines. To couple to this output shaft, you will be required to shorten the stickout length.
1981-90 FJ60/62 when using the NV4500 you are required to fabricate a new crossmember.
