Upgraded Supercharger Belt Tensioner

Moss has developed a new style belt tensioner for JR M45 supercharged MX-5s, which is now used as standard in all system kits. This new tensioner assembly eliminates belt slipping issues by allowing for more adjustment, especially useful on higher boost systems. The belt now runs in the centre of the idler pulleys and not to one edge or the other. Belt changes are simpler and less time consuming. The kit also includes two new idler pulleys. The kit is only compatible with cars that have power steering (PS) and belts should be purchased separately depending on specification of your car and supercharger installation.
