Yokomo RD/SD/MD Aluminum Lightweight Spur Gear Hub

Yokomo RD/SD/MD Aluminum Lightweight Spur Gear Hub The Yokomo RD, SD, and MD Aluminum Lightweight Spur Gear Hub is an optional upgrade designed for the Rookie Drift, Super Drift, and Master Drift platforms when paired with the Yokomo Aluminum Top Shaft (YOKRD-631 - sold separately). Its larger diameter improves the spur gear's hold for smoother, more stable rotation during operation. Rotation Stability & Drivetrain Efficiency This lightweight aluminum hub enhances drivetrain feel by positioning the spur gear closer to the gear case, reducing stress on the top shaft during rapid acceleration. The refined placement supports a more direct and responsive throttle sensation, while the stylish machining contributes to a clean, performance-focused appearance. Its improved rotational stability helps maintain consistent gear engagement, making it a valuable upgrade for drift drivers seeking smoother output and reduced drivetrain wobble.
