Fits HPI Savage X, XL, 21, 25, SS, and 4.6 series trucks

This is the Team Integy 48-Tooth Steel Spur Gear for the HPI Savage X, XL, 21, 25, SS, and 4.6 Series trucks.  These are much stronger than the stock plastic gear.  This is one of the first upgrades you should make to your truck.  The color-coded rings make gear identification much easier if you have several different steel spur gears.  The fewer number of teeth the spur gear has, the more top-end speed the vehicle will have.  The higher the number of teeth the spur gear has, the more acceleration the truck will have.
