Leave it to Dynatrac to re-design and improve on a 20-year old design that is essential to reliable four-wheeling.

The DynaLoc Locking Hub from Dynatrac is new from the ground-up, offering improved function, greater strength, better clearance, and an attractive design, all MADE IN THE USA. 3-times stronger than other Dana 60 Locking Hubs. First truly new locking hub design in 20 years. Gears MADE IN THE USA from heat-treated, chromoly steel. Unique gear tooth design won't disengage under high torque load. Low profile knob assembly decreases impact with rocks and obstacles. Attractive stainless steel bezel resists impact and scrapes along rocks. Defaults to locked position for reliable operation. Models available for 35 and 40-spline shafts. Bolt-on installation. Upgrades locking hubs on Ford, Dodge, and Chevy trucks equipped with Dana 60 front axles from '78-'04.
