Tech Note 2: Plastic Dial Hub-Locks
Spicer made external mount Plastic Dial free-wheel Hub-Locks from the late 1960's to the mid 1970's. These Hubs were the factory original equipment parts for both to Ford and GM 3/4 ton 4x4 trucks with Dana 44 front axles. They were also used on Ford F-250 Crew Cab trucks with Dana 60 closed knuckle front axles from 1974-1975. Most parts for these hubs have been out of production for decades so parts availability is becoming quite limited.
