New heavy duty machined spur gear with alloy mounting plate for the HPI D4 series. The machined 7075 mounting plate with its 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 included machined delrin spur gear does not flex like the stock spur gear so will reduce stripped gears. A 72 spur gear is included. We also offer an optional 68 tooth spur gear separately for stock spec class gearing.

Includes M2x4 steel hardware.

$22.95 MSRP
