This Yokomo SD-S70A 70T spur gear is a direct-fit replacement for Yokomo drift-series models built on the Drift Package and Drift Racer platforms. Its integrated hub mounts directly to the rear input shaft so you do not need a separate hub adapter.
Keep this part as a spare for worn gear replacement or for faster swap-outs during routine maintenance. The design restores reliable gear engagement and simplifies drivetrain servicing at the track or in the workshop.
