Replacement spur gears for the slipper and transmission. Select the tooth count and pitch to match your drivetrain. 32dp options fit 4X4/VXL Rustler, Slash and Stampede; Mod 1 options fit Maxx, X-Maxx and XRT. Steel versions handle high-power brushless setups. (A few options are fitment revisions of the same tooth count — pick by your truck's existing gear.)
