Differential Gear Kits

Differential Gear Kits

AAM kits are packaged with the replacement parts industry in mind. Each differential gear kit contains authentic side and pinion gears that were included with the axle when the vehicle was built. Each gear set is built to withstand the high level demands in terms of noise, vibration and harshness reductions that OE vehicle manufacturers require. Net shape gears deliver the fit and performance the replacement market demands while providing a low manufacturing cost to keep the repair bill as affordable as possible.
