This aftermarket adapter and hardened gear set is intended for the TRAXXAS Slash 4X4 low-CG 68086-21 transmission. The combination of a lightweight aluminium low-CG adapter and hardened 32-pitch steel 54T spur with an 18T pinion is specified to deliver stable torque transfer and improved wear characteristics within the driveline.
Engineering notes: the aluminium adapter reduces mass at the gearbox interface to help lower the centre of gravity, while the hardened steel spur and pinion provide wear resistance under repeated load cycles. The 32-pitch specification aligns with the Slash 4X4 low-CG transmission requirements for this version.
Fitment and tuning guidance: after installation confirm correct gear mesh and backlash, ensure the pinion set screw engages the motor shaft flat, and verify there is no binding of the motor shaft or spur carrier. Monitor bearing condition and perform small mesh adjustments during break-in to optimise noise levels and drivetrain efficiency.
For lower gearbox mass and long-life steel gearing choose this aluminium low-CG adapter with hardened 32-pitch gears to maintain consistent power delivery on the Slash 4X4 low-CG 68086-21 platform.
