Overview

Upgrade your off-road or drag racing vehicle's performance with the Yukon Gear Differential Spool designed for rear Dana 44 differentials. This spool replaces the stock differential, instantly transforming it into a 100% lockup system, ensuring maximum power distribution to both rear wheels. Designed for use with 30-spline axles, the Yukon Gear Differential Spool is a perfect fit for vehicles equipped with a 3.73-ratio and lower gears. Crafted from premium 8620 steel and heat-treated for exceptional durability, this spool is engineered to withstand extreme conditions. Please note that this spool is not recommended for street-driven rides due to its locked differential design, which can lead to challenging maneuverability on paved surfaces.
