The GPM CRA156014T kit upgrades the Traxxas Craniac with a lightweight aluminium spur adapter and hardened steel 60T and 14T gears to give a more durable drivetrain suited to rough terrain work.
Combining aluminium and steel yields a resilient setup that stands up to repeated shocks and hard landings, maintaining consistent gear engagement under load.
This set is cut to match the Craniac gearbox profile so fittings align with standard mounting points for a quick swap in the field or workshop.
