TRAXXAS SLASH 4X4 Aluminium Low-CG Adapter with 54T Spur and 17T Pinion SLA155417TLG by GPM  [SLA155417TLG]

Low centre aluminium adapter paired with hardened steel gears

This aftermarket GPM kit replaces the original gear interface on TRAXXAS SLASH 4X4 Low-CG units intended for the 68086-21 version. It pairs an aluminium low-CG adapter with hardened steel spur and motor gears to maintain steady torque transfer without modifying the drivetrain layout.

The objective is to keep a low centre of gravity using the aluminium adapter while upgrading to hardened 32-pitch steel gears to increase wear resistance and consistent meshing. Included are a 54T steel spur and a 17T steel motor gear, giving a single defined spur/pinion pairing compatible with the Slash 4X4 68086-21 build.

Reference driven ratios for common pinion sizes are: 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. The supplied 17T motor gear balances acceleration and top speed for standard Slash setups.

Use this set when you prioritise a robust steel gear mesh while retaining a low-CG aluminium adapter on a Slash 4X4 configured around the 68086-21 variant; the upgrade targets driveline consistency rather than chassis changes.
