This aluminium belt tension cam holds bearings at both differential ends, for one-way and spool types, and lets you change belt tension by rotating both sides at the same time. It is supplied as a scale replacement to preserve bearing alignment and permit measured belt preload adjustments on suitable touring car chassis.
Choose this cam when you need even tension changes without altering mount positions: turning the cam halves together raises or lowers belt tension while bearing locations remain secure. The design aims for reliable adjustment and ease of service rather than modifying suspension geometry.
