This aluminium gear adapter set is an RC-scale drivetrain component designed for the TRAXXAS Slash 4X4 platform, supplied by GPM as SLA155619TLG. The adapter pairs an aluminium low-centre-of-gravity mounting piece with hardened steel, 32-pitch gears to deliver a consistent transfer of power to the drivetrain without implying any real-vehicle application.
Use this set where you need a direct replacement or an aftermarket alternative for the 68086-21 version. The steel 56T spur and matching 19T motor gear are intended to reduce gear deformation and maintain repeatable mesh under load, supporting tuning choices focused on traction and motor responsiveness.
Technically focused, this adapter set is suited for modelers aiming for durable gear mesh and a lower centre of gravity on the TRAXXAS Slash 4X4 68086-21 version; fitment and final ratio depend on the chosen pinion size.
