New heavy duty machined spur gear with alloy mounting plate for the HPI D413. The much stronger machined delrin spur gear does not flex like the stock spur gear so will reduce stripped gears. Includes the machined 7075 mounting plate. The 2 piece design makes for easier spur gear changes- you do not have to open the gear diff and remove outdrives with our 2 piece design.
The alloy mounting plate also provides cooling of the diff fluid for more consistent diff action.
A 72 spur gear is included. We also offer a spare 68 tooth spur gear separately for stock spec class gearing.
Includes alloy steel hardware.
