Advance Adapters NV4500 to GM NP205 Transfer Case Adapter - 29 Spline - 50-9552

The Advance Adapters NV4500 to GM NP205 Adapter Assembly is designed to mate a Dodge 4WD NV4500 manual transmission with a GM NP205 transfer case featuring the circular six-bolt front pattern. This adapter converts a Dodge 29-spline NV4500 output to work with a GM NP205 using a new 29-spline female NP205 input shaft and gear.

This kit is intended for use with the GM part-time NP205 transfer case used in 1985–1991 GM one-ton trucks. The GM NP205 is a cast-iron transfer case with a circular six-bolt mounting pattern and a passenger-side front output. The adapter assembly includes all major components and hardware required for installation.
