TRAXXAS SLASH 4X4 Low-CG Aluminium Gear Adapter 56T Spur 20T Pinion SLA155620TLG by GPM  [SLA155620TLG]

Lowered-CG aluminium adapter for Slash 4X4 drivetrains

This aluminium adapter set pairs a low-centre-of-gravity aluminium adapter with hardened steel 32-pitch gears, supplied as a 56T spur and 20T motor pinion. It is designed as a drop-in aftermarket drivetrain component for the TRAXXAS SLASH 4X4 running the 68086-21 layout.

Materials are aluminium for the adapter and hardened steel for the spur and motor gear, all using a 32 pitch tooth profile. The hardened steel gears keep tooth engagement consistent under load while the lower adapter profile reduces the rotating height to keep the gear mesh closer to the chassis centreline.

Gear ratio guidance follows the fixed 56T spur with selectable motor pinions. The included 20T pinion produces a 56T to 20T ratio of 1:2.800. For reference, other common pinions with a 56T spur yield: 13T=1:4.307, 14T=1:4.000, 15T=1:3.733, 16T=1:3.500, 17T=1:3.294, 18T=1:3.111, 19T=1:2.947.

Installation notes: this adapter matches the 32 pitch tooth form and standard mounting points for the specified Slash 4X4 version. When fitting, set correct motor mesh and backlash, secure the pinion to the motor shaft with the original fastener, and confirm spur alignment in the gearbox to avoid premature tooth wear.

Tuning role: run different pinion sizes on the 56T spur to change acceleration versus top speed; the supplied 20T pinion is a mid-range choice that leans toward higher top speed on common brushed and brushless setups while keeping motor load moderate.

This GPM SLA155620TLG kit provides a low-CG aluminium adapter paired with hardened steel 32-pitch gears for TRAXXAS SLASH 4X4 cars using the 68086-21 version, ideal for builders wanting a lower drivetrain profile and standard 32-pitch gear compatibility.
