TRAXXAS SLASH 4X4 LOW-CG Aluminium Gear Adapter with Steel 32 Pitch 56T Spur & 20T Pinion by GPM SLA155620TLG  [SLA155620TLG]

Low-CG aluminium gear adapter for Slash 4X4

This GPM aluminium adapter set pairs a low-centre-of-gravity aluminium gear adapter with hardened steel 32-pitch gears, supplied as a 56T spur and 20T motor pinion. It is intended as a drop-in aftermarket drivetrain item for the TRAXXAS SLASH 4X4 platform that uses the 68086-21 version layout.

Materials are stated as aluminium for the adapter and hardened steel for the spur and motor gear, retaining a 32 pitch tooth profile. The steel gears aim to deliver consistent tooth engagement under load while the aluminium adapter reduces rotating mass height to keep the assembly closer to the chassis centreline.

Gear ratio options follow the fixed 56T spur in combination with various motor pinions. The set includes the 56T spur and a 20T motor pinion which yields the following ratio when paired together: 56T with 20T = 1:2.800. Other ratios commonly used with a 56T spur are shown for reference: 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 set matches the 32 pitch tooth form and standard mounting locations of the specified Slash 4X4 version. Check motor mesh and backlash during fitting, secure the pinion to the motor shaft using the original fastening method, and verify spur alignment within the gearbox to avoid premature tooth wear.

Tuning role: use the 56T spur with different pinion sizes to adjust acceleration versus top speed characteristics; the supplied 20T pinion is a mid-range option that leans toward higher top speed on typical brushed and brushless setups while keeping motor load moderate.

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