TRAXXAS Slash 4X4 Low-CG Aluminium Gear Adapter 32-Pitch 54T Spur 18T Pinion SLA155418TLG by GPM  [SLA155418TLG]

Low-CG aluminium adapter and hardened steel gear set

This RC gear adapter and matching spur and pinion are produced for the TRAXXAS Slash 4X4 low-CG 68086-21 transmission. The kit combines a lightweight aluminium low-CG adapter with hardened 32-pitch steel 54T spur and 18T pinion gears to keep torque transfer consistent across the driveline.

Materials and role in the drivetrain: the adapter uses aluminium to reduce mass at the gearbox interface and lower the centre of gravity, while the spur and pinion are hardened steel to resist wear during repeated use. The 32-pitch gearing aligns with the Slash 4X4 low-CG transmission standard for this version.

Fitting and setup tips: set correct gear mesh and check backlash after installation, ensure the pinion set screw is secure, and verify the motor shaft and spur carrier rotate freely without binding. Small mesh tweaks and good bearing condition will influence drivetrain noise and mechanical efficiency. This component suits standard 1/10 scale electric truck assembly and tuning routines.

Calculated gear ratios

• 54T with 15T = 1:3.600
• 54T with 16T = 1:3.375
• 54T with 17T = 1:3.176
• 54T with 18T = 1:3.000
• 54T with 19T = 1:2.842
• 54T with 20T = 1:2.700

Choose this aluminium adapter and hardened steel 32-pitch gears when you want a lower gearbox centre of gravity and durable steel gearing for steadier power delivery on the Slash 4X4 low-CG 68086-21 platform.
