Differential Spider Gears
Differential spider gears are the small bevel gears inside the carrier that allow the two drive wheels to rotate at different speeds through turns. Worn or broken spider gears cause clunking, binding, or complete loss of drive on one wheel, and replacing them is a common differential service for high-mileage vehicles, drag cars, and off-road builds that see heavy torque loads.Popular Differential Spider Gear UpgradesHeavy-duty spider gear kits from Yukon Gear and Spicer are available for Dana 44, Dana 60, GM 10.5-inch, and Ford 9-inch differentials. Stronger forged steel spider gears are popular on high-horsepower drag builds and loaded tow rigs where OEM cast gears fail under sustained torque. Some upgrade kits include new cross shafts, thrust washers, and spider gear pins for a complete open carrier refresh.How do I know if my spider gears are worn?Common signs include a clunk during low-speed turns, uneven tire wear on one drive wheel, and metal debris visible in the gear oil dur...
