The H series engines are known to have an excessive amount of belt flap along the long front side of the timing belt, especially on engines with aftermarket cams and at high rpm. We designed this secondary tensionner to eliminate this problem, reducing the chances of a skipped tooth. We have seen as much as 25mm of belt flexion during dyno testing, this flex is also making slight changes in the whole cam and crankshaft timing.

Instead of over tightening the belt with the primary tensioner like most people do to deal with this common problem, which typically ends up messing the front cam bearing journals in the head and belt walking off the gears, you can set the tension just like you would on a completely stock motor with this product. 

*this will only fit on cars that have power steering deleted as it bolts right on the head where the power steering pump is normally mounted.

*This kit is intended for use with H series VTEC head applications. It will not work with non-VTEC heads.


All components are CNC machined from T6061 billet aluminum
