This is the 4 Bevel Gear Differential Conversion Set for the HPI Savage X, XL, 21, 25, and Savage SS trucks, as well as the HPI R40 Touring Car. This set converts one standard gear diff to a 4 bevel gear diff, or replaces the gears in vehicles that come with the 4 gear diffs from the factory. For enough parts to replace the front and rear diff gear sets, purchase a quantity of "2" packages of these. If you have a high-performance vehicle, you may want to keep a set or two in your toolbox because differential gears do wear out over time.
