HRGRM37C - CNC Steel Diff Outdrive GROM

This product is a CNC machined steel differential outdrive designed to replace the stock plastic or stamped steel outdrives used in many Arrma ARA311178-series differentials. The robust steel construction increases strength and resistance to wear under high torque loads, reducing the chance of breakage during aggressive driving. Precision machining ensures accurate fit and smooth engagement with spider gears and axle components. Its design maintains correct geometry for reliable power transfer while enhancing durability over stock parts.
