The GPM SLA155420TLG assembly pairs a CNC machined aluminium gear adapter with hardened steel 32 pitch 54T spur and 20T motor gears to reduce deflection and improve load distribution in the TRAXXAS Slash 4X4 driveline. Tight machining tolerances promote reliable gear mesh under high torque, and the low centre of gravity adapter helps maintain chassis balance while enhancing durability for repeated high stress runs.
