Cut Resin Cam for Tighter Belt Control

The Yokomo B9-BTCBA Precision Resin Belt Tension Cam is a precision-cut resin component engineered to reduce slack and improve drivetrain feedback. Its one-piece construction and accurate profile make it a reliable upgrade for competitive and hobbyist builds alike.

Benefits of a Cut Resin Component

Being machined rather than cast, the cam maintains consistent geometry that lowers the chance of belt drift and uneven tension. That results in steadier acceleration and cleaner steering inputs during aggressive runs.

Broad Yokomo Chassis Fitment

This cam suits many Yokomo platforms across the MRTC and MSR ranges listed below. It is built to match existing belt layouts and mounting points so installation is straightforward.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is this cam a direct bolt-in replacement?

In most cases it replaces the original cam without modification, but confirm the part orientation and hardware match your chassis before final assembly.

Will it affect gear mesh or pinion alignment?

The cam focuses on belt tension rather than gear mesh, but any change to drivetrain components should prompt a quick check of gear alignment to avoid premature wear.

How does it handle off-road impacts?

Resin cams offer good precision but inspect after hard hits; if you run rough terrain regularly, include the cam in your post-run checks to ensure no cracking or distortion.
