Installation Notes and Tips

Verify shaft diameter, housing bore, and transfer case type before installation. Clean the bore and shaft surface thoroughly, and inspect for grooves, corrosion, or wear that could affect sealing. Confirm the vehicle uses the New Process 205 Transfer Case with part-time 4WD and 2-speed operation before ordering. National 2287 is commonly used on 1969-1993 Chevrolet, Dodge, Ford, and GMC NP205 applications, including 1976-1979 Ford Bronco, 1975-1980 Chevrolet K20, and 1981-1993 Dodge W350 listings.
