Parts for New Process NP200 NP201

The left drive, gear driven, New Process NP200 remote mount transfer case was used in production 4x4s from 1946-1978, plus it also found in a wide variety of industrial equipment including Timberjack log skidders. The NP200 can be identified by it's dual rear output shafts. The upper shaft usually incorporates a parking brake mechanism and the lower shaft is the output to rear axle. The NP200 used in Dodge, International, and Jeep 4x4 trucks features a 1:1 ratio high range and a 1.96:1 low range. Under modern highway conditions, NP200 transfer cases use more power and run much hotter than later model cases as the power transfer path in all ranges is through all three shafts. Strength wise, the NP200 is more than capable of handling the relatively low horsepower straight 6 and V8 engines it was originally driven by, but the 1-3/8", coarse spline output shafts are inadequate for repower conversions with high torque modern engines. The NP200 was used in 1946-1968 Dodge civilian 1 tons, 1951-1968 Dodge M37, M43 series military 3/4 tons, 1967-1969 Jeep M715, M725, M726 series 1-1/4 ton military trucks, 1969-1974 Dodge export model WM300 1 tons, and in small numbers by International prior to 1956. 

In the mid 1950's, New Process redesigned the NP200 to make the closely related NP201. The primary external difference between the NP200 and NP201 is the location of the rear output shaft. With the NP201, the rear output shaft is inline with the input shaft, so power transfer in 4x2 high range is directly from the input shaft to the rear output shaft. The inline design means the idler and front output shafts are not used to transfer power in 4x2 high range resulting in cooler and more efficient operation. Also, with the NP201, the rear differential pinion can be centered instead of offset to the left side as was required with the NP200. The NP201 was used by International from late 1955 until early 1960 and by Dodge in 1957-1968 civilian based W100, W200, and W300-Series 4x4 trucks. The NP201 was replaced by the New Process NP202 in International 4x4s in 1960 and by the New Process NP205 in Dodge W-Series civilian 4x4s in 1969.

product note

Most NP200 Transfer Cases have 10 spline input and output shafts, but there was a heavy-duty version with a 35 spline input. U-Joint sizes for various applications ranged from tiny Detroit 7260 series to very large Spicer 1480 series. Applications with a parking brake use a companion flange instead of an end yoke on the rear brake shaft (NP200) or rear output shaft (NP201).
