MANUAL CAM CHAIN TENSIONERS

APE manual cam chain tensioners are designed to replace the automatic and hydraulic tensioners on high performance engines. The automatic adjusters can back out when the throttle is closed suddenly at high rpm. This allows the cams to go momentarely out of time, and can result in bent valves and/or serious engine damage. Hydraulic tensioners have a tendency to put too much tension on the chain guide under high rpm/high oil pressure conditions, resulting in premature wear. Both problems can be eliminated with the installation of the APE manual tensioner.

No mater what the engine does, the cam chain tension will remain constant. AnAPE manual cam chain tensioner is a must for any kind of performance riding. APE manual tensioners are CNC machined from billet alloy to exact tolerances for perfect fit. All manual tensioners are priced $51.65
