Yokomo B9-BTCBA Precision Resin Belt Tension Cam - Race Prep Variant  [B9-BTCBA]

Optimise Belt Tension with a Precision Resin Cam

The Yokomo B9-BTCBA Precision Resin Belt Tension Cam is a CNC-style machined resin part built to stabilise belt tension and sharpen drivetrain feedback. Its refined surfaces and consistent geometry help reduce belt play that can dull on-track performance.

Why Machine Work Improves Fit

Machining yields repeatable dimensions that improve how the cam seats in its mount, which in turn cuts down on lateral movement in the belt. That stability translates into more predictable acceleration and steering response.

Works with Many Yokomo Chassis

This cam is compatible with a wide set of Yokomo models, including both MRTC and MSR series shown below. It is crafted to match the belt paths and mounting points common to these platforms, simplifying upgrades and repairs.
