What is Vehicle Type G?

Vehicle Type G includes Dodge light-duty D-Series and W-Series trucks built from 1957 through 1971. This group covers both 2WD and 4x4 models, including pickups, Town Wagons, Town Panels, and related utility vehicles.

W100 / W200 = 4x4 models
D100 / D200 = 2WD models

These trucks share many body, engine, and chassis parts, with the biggest differences being the front axle, transfer case, and related driveline components.

W100/200 Main distinguishing features:

4.10 rear axle gear ratio (standard)
4.09 front axle gear ratio (standard)
NP201 2-speed transfer case (1957-68)
NP205 transfer case (1969-71)
Dana 44 closed knuckle front axle
1957-60 Power Giant models use the earlier wraparound windshield cab
1961-71 models use the later wider cab design

D100/200 Main distinguishing features:

I-beam 2WD front axle
No transfer case
Shares many parts with W-Series trucks except for front axle and driveline components

Engines available for D-Series & W-Series trucks were:

225 Slant 6 (1961-71)
318 V-8 (1959-71)
230 Flathead 6 (1957-60)
315 V-8 (1957-58)

1957-58 W100 models were equipped with either floating or non-floating Dodge Corporate rear axle assemblies. W200 1957-60 models were equipped with a Dodge Corporate floating rear axle assembly, and both used 6-hole wheels. 1959-68 W100 and 1961-71 W200 models used the Dana 60 rear axle assembly equipped with 8-hole wheels. 1969-71 W100 models had a non-floating Dodge Corporate rear axle assembly and used 5-hole wheels.

W100 (1957-71) models and 1957-60 W200 models used the 3000-pound Dana 44 front axle assembly, while 1961-71 W200 models were available with either the 3000 or 3500-pound Dana 44 front axle assembly.

The older style front sheet metal (1957-60) was continued until 1966 in the Town Wagon and Town Panel W100 series trucks. Pickups were built with either the Utiline (step-side) or Sweptline (fleet-side) bed, with various lengths available. 1957-60 trucks and 1957-66 Town Wagon/Town Panel models are distinguished by the wraparound windshield and vertical hinge pillar post. Later 1961-71 cabs have a sloping hinge pillar post and a considerably wider cab. Rear windows were available in 2 sizes.

1961-71 D-Series (2WD) Dodge vehicles such as D100 and D200 share many of the same parts with the 1961-1971 4x4 W-Series vehicles. The D-Series two-wheel-drive trucks use different front axles and driveshafts. Nearly all other parts should be interchangeable between D-Series and W-Series Dodge vehicles.

Because these trucks were never ordered in large quantities by the Military, spare parts availability is more difficult; however, we do have a large stock of many parts for these vehicles.
