Designed and manufactured by Harrop Engineering the HTV 8PK Heavy Duty Tensioner is stronger and more durable that the cast OEM unit.

The Harrop HD Tensioner kit is suited to suit VT-VZ running a Harrop HTV Supercharger as it replaces the stock tensioner and mounts directly to the RHS cylinder head using existing thread holes. With 40 degrees of tensioner rotation coupled with the ability to change the position of the anti-rotation bolt this provides 240% greater load at operating extension compared to the sock tensioner.
