TRAXXAS Slash 4X4 Aftermarket Low-CG Gear Adapter 32-Pitch 54T/18T SLA155418TLG by GPM  [SLA155418TLG]

Aluminium low-CG adapter paired with hardened steel gears

This gear adapter and matching gear set is built for the TRAXXAS Slash 4X4 low-CG 68086-21 transmission. It combines a reduced-mass aluminium adapter with hardened 32-pitch steel spur and pinion gears to maintain reliable torque transfer across the drivetrain.

Component materials and function: the aluminium adapter helps reduce weight at the gearbox interface and lowers the centre of gravity, while the hardened steel 32-pitch spur and pinion are selected to resist wear during regular running. The sizing follows the Slash 4X4 low-CG transmission standard for this version.

Installation advice: after fitting, check and fine-tune gear mesh, confirm the pinion set screw is correctly seated, and spin the motor and spur carrier to ensure no binding occurs. Regularly inspect bearings and recheck mesh after initial runs to settle the gears for quieter operation and consistent efficiency.
