TRAXXAS Slash 4X4 Low-CG Aluminium Gear Adapter with Hardened 32 Pitch 56T Spur & 17T Motor Gear SLA155617TLG by GPM  [SLA155617TLG]

Low-centre aluminium adapter and hardened 56T/17T gear pair

The kit includes a low-centre aluminium gear adapter matched to hardened 32 pitch steel spur and motor gears for the TRAXXAS Slash 4X4 Low-CG configuration. The aluminium adapter improves mounting stability while the steel 56T spur and 17T motor gear increase resistance to wear under regular tuning and higher loads.

Installation pointers: this adapter replaces the original plastic adapter on the 68086-21 variant and secures the 56T spur to maintain correct tooth engagement with the motor pinion. Always hand-rotate the drivetrain after installation, set appropriate backlash and adjust shims or pinion height to avoid binding and protect the Low-CG layout.

Tuning overview: pinion changes alter final drive and vehicle feel. The supplied 56T spur with a 17T motor gear gives one ready ratio, and the hardened-steel gears help preserve tooth life when trying different pinions for circuit or off-road sessions.

• Provided gear pairing ratio reference for 56T spur with various motor gears:
• 56T with 13T = 1:4.307
• 56T with 14T = 1:4.000
• 56T with 15T = 1:3.733
• 56T with 16T = 1:3.500
• 56T with 17T = 1:3.294
• 56T with 18T = 1:3.111
• 56T with 19T = 1:2.947
• 56T with 20T = 1:2.800

A practical upgrade for those who want a robust steel gear pairing mounted to an aluminium adapter on the Slash 4X4 Low-CG 68086-21; confirm mesh and pinion selection before use.
