The only 1 ton exceptions are a few 1975 W300 trucks with the Model 70 closed knuckle axle, and a small number of mid 1980's trucks with wimpy Model 44 axles that Dodge badged as W-350 1 ton models. You will find these fine axles in almost all Dodge 1 ton models from 1975 to 1993, plus all the 1989 to 1993 Cummins Diesel W250 and W350 4x4s. Except for the differential housing and some differential components, all the parts are interchangeable between the two models. The model 61 is basically a modified Model 60 with a different ring gear offset to accommodate a larger diameter pinion gear. Model 61 axles can be found in 1987 to 1993 model year trucks with 3.07 or 3.54 ratio gear sets. Available factory gear sets over the years included 3.54, 4.10, 4.56, 4.88, and 5.86 ratio ring and pinions. The only major design change during the 18 year production run of this axle was a change in 1990-1991 from wheel hubs using externally mounted free wheel hubs (or drive flanges) to hubs with splined internal mount lockouts. The wheel bearings are serviceable and the dead-spindle configuration allows the use of lockout hubs. The Model 60 as used by Dodge from 1975 to 1993 has very durable greaseable king pins and disc brakes. The newly released Model 60 axle used the same size axle universal joint as the previous Model 70 closed knuckle axle, but the new open knuckle design had a sharper turning angle which substantially improved vehicle maneuverability. We stock a complete line of parts for the open knuckle, Dana-Spicer Model 60 Front Axle which was first used by Dodge in the 1 ton W300 4x4 trucks for the 1975 model year. Except for wheel hubs and brake rotors, 1975-1993 Dana 60 front axles share a high percentage of the same parts for all years. Shop now for Parts, Tools, and Shop Manuals specific to 1975-1993 W200, W250, W300, W350 4x4 trucks with Dana 60 Front Axles.
