This aluminium belt tension cam secures bearings at both ends of the differential, for both one-way and spool configurations, and allows belt tension changes by rotating both halves in unison. It is intended as a scale replacement to preserve bearing alignment and permit controlled belt preload adjustments on compatible touring chassis.
Use the cam when you need uniform tension control without moving mounts: turn the cam halves together to raise or lower belt tension while bearing positions stay locked. The component emphasizes durability and serviceability, not modification of suspension geometry.
