J'S RACING REINFORCED CHAIN TENSIONER - K20 / K24

Reinforced chain tensioner for K20 and K24. In the case of hard engine braking during sports driving or sudden overruns, the genuine hydraulic chain tensioner causes slack in the chain due to insufficient operating force. As a result, the valve timing may shift and, in the worst case, may cause engine blow.

By installing this product with reinforced specifications, it is possible to minimize the deviation of the valve timing at high rotation, and it is possible to significantly reduce the possibility of engine blow. This is an essential item for sports driving (especially when the high camshaft is attached). Widely applicable from street to circuit driving.
