Description
TK2051 Torque King® Premium Quality Complete Gasket and Seal Kit for 1969-1984 Chevy and GMC New Process NP205 gear drive transfer case with 10 spline input shaft feature Original Equipment Spec Precision-Thickness Gaskets, Genuine New Process Rear Output Yoke Spline Seal, and North American Made Original Equipment Quality Input/Output/Shift Rail Seals. Our Torque King® Premium quality Complete Gasket and Seal Sets are assembled with highest quality components for your specific NP205 application and are the most complete application specific NP205 Gasket and Seal Sets you can buy. Competitive Kits are assembled for generic applications so they rarely include all components required for your exact application, plus these generic kits use parts that do not even come close to meeting original equipment specifications to achieve a lower price when compared to original equipment parts such as those found in Torque King® Premium Gasket/Seal Kits for your Chevy or GM 4x4.

Tech Note 2: GM NP205
General Motors used direct mount New Process NP205 Transfer Cases from 1969 to 1991. The 205 was available on all full size 4x4 body styles up to 1980. From 1981 through 1991 the 205 was the only available in 1 ton K and V series square body style 4x4s.
Tech Note 3: Rear Output Seal
For maximum sealing of your fixed rear output yoke or remote mount input and front output yokes with 2-1/8" hubs, order a pair of our optional TK50092 Special Rear Output Seal which can be doubled for 2-1/8" input/output yoke applications.
Tech Note 4: RTV Sealant
Except for the PTO cover on later production models, NO RTV sealant was used on the NP205 Transfer Case or adapter. All shaft, coupler, and bearing clearances were designed for specific thickness cut paper gaskets. RTV sealant SHOULD NOT be used to replace any other NP205 gasket, however, you can use a VERY thin film on one side of a gasket to hold it in place during assembly or to fill in gouges in mating surfaces.
