Free-Spin Kits
The original Dynatrac™ Free-Spin™ Heavy Duty Hub Conversion Kits are popular with off-road enthusiast as well as companies who rely on their Dodge and Ford trucks for work. Free-Spin kits replace problematic unit bearings, eliminating a weak link that is prone to failure. In addition to a significant increase in strength and durability, Dynatrac Free-Spin kits improve fuel economy by reducing the components that spin in the front axle when 4-wheel-drive is not selected, and the kit provides the flexibility and robust design of manual locking hubs.
Watch this video to learn why the Dynatrac Free-Spin is the best hub-conversion kit for your truck:
Dynatrac Free-Spin Kits are designed using OEM data with extensive in-house research and development resources to ensure perfect tolerances for a lifetime of trouble-free operation. As the only 100-percent U.S.-made kit available, the Dynatrac Free-Spin Kits include heat-treated chromoly spindles, top-quality bearings and seals, 35-spline 1.50-inch chromoly outer shafts, wheel hubs, locking hubs (Dynatrac DynaLoc™ or Warn) and all necessary tone rings, studs and hardware. When Dynatrac DynaLoc hubs are used, the Free-Spin Kits offer the shortest hub stickout length on the market, keeping them tucked inside the wheel and tire package better than competitors.
