An important component that's often overlooked when building high power F-series engines is the Timing Chain & Timing Chain Tensioner. The additional stress placed on the factory Timing Chain Tensioner while employing high-lift camshafts can lead to Tensioner failure, and ultimately engine damage.
TODA's F20C/F22C Heavy Duty Chain Tensioner addresses the weak point of the factory tensioner, being the compensator.
This prevents the possibility of damage, and keeps accurate cam timing. This product was originally developed for the TODA N+ endurance racing engines.
