The GPM SLA155418TLG low-center-of-gravity aluminium adapter is precision engineered to lower rotating mass and promote a more stable gear mesh. Combined with a hardened steel spur, this set reduces drivetrain deflection under load and supports consistent torque transfer for demanding running conditions.
Both the spur and pinion are hardened steel to preserve tooth geometry under stress, and the available ratios let you tune the vehicle for quicker acceleration or higher terminal speed as required by your setup:
