APE Pro Series

APE introduces the Pro Series manual cam chain tensioner. This new tensioner is designed for the racer who frequently adjusts his engine. The easy-access socket head adjuster screw is perfect for tight spaces. The interior o-ring design ensures that repeated adjustments will not eventually flatten the o-ring against a jam nut.

APE's Pro Series tensioner features an internal oring and custom-machined adjuster bolt. The bolt is broached with a 4mm hex.
