Description

The Motive Gear MGK-238 is a complete ring and pinion gear kit with a 4.10 ratio for 9.25-inch front and 9.50-inch rear axles. It rebuilds front and rear differentials, addressing issues like differential play or failing bearings (clunking, howling, whining). It's also suitable for regearing after installing oversized off-road tires to improve low-end torque and mileage. The kit includes front and rear ring and pinion gears, Timken bearings, seals, ring gear bolts, alignment shims, differential gaskets, associated hardware, and gear marking compound.
