The Yokomo RS-BTC Belt Tension Cams are precision resin components created to let you set drive belt tension on the RS1.0 chassis. Adjusting cam position alters belt preload and helps you control how the front and rear differentials share drive during cornering and acceleration.
Correct belt tension reduces slop and overheating while keeping drivetrain inputs predictable. The RS-BTC cams let you move through set positions to find a balance between minimal drag and reliable engagement, ensuring smoother runs overall.
These cams are intended for RS1.0 platforms, including RSR-010 and RSR-LFGT3RTR variants, and install without the need for chassis modification. They are a straightforward upgrade for anyone looking to refine handling without complex alterations.
