Tuning-oriented belt tension cam

This aluminium belt tension cam secures bearings at either end of the differential, supporting one-way and spool units, while enabling belt tension adjustment via synchronized rotation of both cam halves. It serves as a replacement part to keep bearing alignment and give tuners a simple way to alter belt preload on compatible touring car setups.

Use the cam when precise belt preload is needed to affect drivetrain response: adjusting both halves together changes slack and can influence overall power delivery and feel without relocating mounts. The unit is focused on functional adjustment and easy service rather than suspension geometry changes.

Packing includes

  • Belt tension cam - 1 pcs
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.

How does belt tension affect handling?

Increasing belt preload can reduce drivetrain lash and improve throttle response, while too much tension may add drag; use small incremental adjustments and test lap feedback.

What is the best way to tune with this cam?

Rotate both cam halves equally to set a baseline tension, then adjust in small steps while noting changes to traction and acceleration on your BD7, BD5 or DRB chassis.

Can tension tweaks improve lap times?

Yes, careful belt preload tuning can refine drivetrain response and help extract better consistency from the car, but always validate changes through controlled test runs.
