Yokomo B7-BTC Belt Tension Cams for BD7/BD5/DRB, resin belt cams, 4 pcs  [B7-BTC]

This Yokomo B7-BTC set is a pack of belt tension cams designed for 1/10-scale RC touring chassis. The parts are moulded in lightweight resin to provide minimal added mass while allowing quick adjustment of belt tension without changing bulkier components. Each purchase contains four individual cams to replace or tune both sides of the drivetrain on compatible platforms.

Functionally the cams locate on the belt path to alter tension point and take-up, offering a simple way to refine drive feel and belt stability during setups. Installation is straightforward for anyone familiar with belt-drive touring cars, requiring removal of the relevant belt cover and swapping the existing cams in place. Keep this as an RC-scale accessory and follow chassis-specific service steps rather than general automotive procedures.

Tuning notes: small incremental changes to tension are recommended, checking belt alignment and runout after each adjustment. Because the cams are resin, avoid over-tightening adjacent fasteners to prevent deformation. These parts suit hobby mechanics who want a low-mass option for fine-tuning belt behaviour on the listed chassis.
