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

Low-profile aluminium adapter tailored for Slash 4X4

This aluminium adapter kit combines a low-centre aluminium mount with hardened steel 32-pitch gears, supplied as a 56T spur and 20T motor pinion. It is intended as an aftermarket drop-in option for TRAXXAS SLASH 4X4 platforms that follow the 68086-21 layout.

The adapter is made from aluminium while the spur and pinion are hardened steel, maintaining the 32 pitch tooth profile. The hardened steel gears provide steady tooth engagement under load and the reduced adapter height keeps the gearset nearer the chassis centreline.

Ratio notes: the kit fixes a 56T spur and is compatible with various motor pinions. The included 20T pinion yields a 1:2.800 ratio when paired with the 56T spur. For comparison, other pinion sizes on a 56T spur produce these ratios: 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.

Fitment advice: this set matches standard 32 pitch mounting and the specified Slash 4X4 mounting points. During installation confirm correct motor mesh and backlash, secure the pinion with the original fastening method, and align the spur inside the gearbox to limit premature wear.

Tuning guidance: changing pinion size on the 56T spur alters acceleration and top speed tradeoffs; the supplied 20T sits in a mid-to-high top speed range while keeping motor load reasonable on typical brushed or brushless setups.

The GPM SLA155620TLG delivers a low-centre aluminium adapter with hardened steel 32-pitch gears for TRAXXAS SLASH 4X4 using the 68086-21 version, useful for racers and hobbyists aiming for a lower drivetrain profile and standard gear compatibility.
