Description

The Yukon spider gear kit is designed as a replacement component for Ford 8.8-inch Trac Loc Positraction differentials. Specifically engineered for 31 spline axles, this kit ensures a complete and proper spider gear set replacement. Yukon Gear & Axle spider gear kits are manufactured using higher quality materials and improved techniques compared to OEM parts, aiming for a longer lifespan. This particular kit includes two side gears, two pinion gears, a cross pin shaft, a cross pin bolt, and spider gear thrust washers, providing the necessary components for the replacement. It is important to note that this is a bare spider gear kit and does not include clutches, pinion gear thrust washers, or a separate cross pin shaft. The product comes with a one-year limited warranty against manufacturer defects.
