Motive Gear is a division of Midwest Truck and Auto Parts, and has the best quality drivetrain parts available currently. Motive Gear has a wider variety of ring and pinion gears than any other aftermarket manufacturer and is the first choice of distributors world-wide. But Motive Gear is about more than just ring and pinion gears and differential bearing kits, and also markets a comprehensive line of transmission and transfer case parts, in addition to replacement axle shafts. With Motive Gear's performance and axle divisions, Motive Gear Performance and TEN Factory, there is no better value in drivetrain parts.
