Transfer Case
This adapter assembly fits 1974 to July 1980 16 spline transfer cases. The drive gear has 16 internal splines and a diameter of 1.259”. The transfer case bolt pattern is the same as the earlier 3 speed transfer cases.

GM 4WD NV4500 (1993-94): During the first two years of the NV4500, Chevy offered this 5 speed with a 6.34:1 1st gear; 2nd 3.44:1; 3rd 1.71:1; 4th 1:1 ratio, and a 27% overdrive. It was also the first year that Chevy changed the bellhousing-to-transmission bolt pattern. This transmission is ideal when converting your vehicle, providing an ultra-low 1st gear. GM, however, only produced this particular ratio during these years. The major complaint of this 5 speed was stiff shifting and noise in 3rd gear.

GM 4WD NV4500 (1995): This transmission is identical to the 1993-94 transmission, except the 1st gear ratio had been changed to 5.61:1; 2nd 3.04:1; 3rd 1.67:1; 4th 1:1 ratio, and a 27% overdrive. The noise and shifting problems had been corrected.

GM 4WD NV4500 (1996-2006): This transmission has the same gear ratio as the 1995 version. Chevy once again changed the bellhousing-to-transmission bolt pattern and went to a larger bellhousing index diameter. This Chevy NV4500 has the same bellhousing-to-transmission bolt pattern as the Dodge NV4500. These transmissions use a GM internal release bearing.

All of the Chevy version NV4500s listed above have a 1-1/8 “ 10 spline input shaft with a pilot tip of .590. The input shaft protrudes from the front of the transmission approximately 6-5/8”. We only offer adapters for the 4WD version of the Chevy NV4500. The stock output shaft on this transmission must be shortened as illustrated on the instruction sheet included with each kit.  

Install notes: Several adapter kits require you to shorten the existing transmission main shaft while it is still in the transmission case. This is common when a 4WD GM NV4500 is being used. Each instruction sheet gives the exact cut off location.
