35-Spline L/W Pro-Race Spool - Dana 60

The 35-Spline L/W Pro-Race Spool for Dana 60 is engineered for serious off-road racers and high-performance enthusiasts who demand absolute traction control and minimal weight in extreme terrain. This pro-level differential component replaces the factory spider gears with a welded spool design, locking both axle shafts together for 100% power distribution to both wheels simultaneously. Purpose-built for rock crawling, desert racing, and trail applications where grip and durability are non-negotiable, the 35-spline spool transforms your Dana 60 into an uncompromising traction device.

Constructed as a lightweight (L/W) design, this spool reduces unsprung mass while maintaining the strength required for high-torque applications—critical when running oversized tires and aggressive gearing on modified trucks and buggies. The 35-spline interface matches Dana 60 shafts directly, ensuring precise engagement and zero slippage under load. Unlike traditional limited-slip differentials or lockers with mechanical engagement points, a welded spool delivers instant, mechanical lock with no delay—every ounce of engine torque transfers equally to both wheels the moment throttle is applied. Weighing 14.23 lbs and fitting within compact Dana 60 housing dimensions (9.8 x 8.8 x 9.8 in), this component is ideal for weight-conscious builds.

This spool suits hardcore off-road competitors, custom truck builders, and trail warriors who run locked axles in both front and rear for maximum terrain capability. Installation requires basic differential service knowledge—removal of the factory differential case, installation of the spool in place of the spider gear assembly, and reassembly with fresh gear oil. Verify your Dana 60 is equipped with 35-spline axle shafts before ordering, as compatibility depends on shaft configuration. The pro-race spool delivers no-compromise traction for vehicles that prioritize performance over street manners, making it essential for serious rock crawlers and extreme-terrain applications.
