The Yokomo B9-BTCB Belt Tension Adjust Cam is a precision machined component designed for BD9 users seeking stable belt tension settings. It assists in achieving even preload across the drive system to promote smoother operation and longer belt life.
Consistent tension reduces drivetrain drag and uneven wear, helping with predictable throttle response. The B9-BTCB cam is a simple way to make controlled changes when testing different track layouts or tyre compounds.
