BD9 front belt tensioner assembly

This is an RC-scale front belt tensioner set intended for use with the BD9 platform. The part replaces the front belt tensioner assembly to restore or maintain correct belt routing and alignment on compatible BD9-derived chassis.

The component is intended strictly as a spare or replacement accessory for hobby RC use; confirm fitment against the supported chassis codes before installation. Typical uses include replacing worn tensioners after extended running or using as a direct spare during setup and tuning sessions.

In setup and tuning, the front belt tensioner affects belt tracking and how the belt reacts under load, so inspect belt alignment and mounting points when fitting this part to ensure consistent belt behaviour during practice and competition runs.

Compatibility
