Yokomo BD-BTCSA Belt Tension Cam Spring and Ball Set - Track Tuning  [BD-BTCSA]

Fine Tune Belt Tension on Yokomo Chassis

The Yokomo BD-BTCSA Belt Tension Cam Spring and Ball Set is built to improve belt adjustment on BD7 and BD5 platforms. The kit contains four springs and four balls that produce a tactile click so you can feel each rotation position and achieve consistent tension. It is a practical upgrade for hobbyists focused on predictable handling and smoother drive response.

Tactile Click for Accurate Adjustments

Made with BD7 and BD5 users in mind, the cam spring and ball deliver an intuitive click when the cam rotates, letting you confirm belt position without guesswork. That feedback makes small tuning steps easier and helps maintain consistent setup between runs.

Works with Multiple Yokomo Models

This set fits a number of Yokomo chassis families, including DP-DIB2, DP-DIB2R, MRTC-BD8 and related models. Whether you are refreshing worn parts or upgrading your setup, the BD-BTCSA parts provide a simple, reliable option across various configurations.
