KEEP ON TRACK.
When running high RPM and under heavy geared breaking the timing belt can “jump” and potentially skip a tooth causing the engine timing to go out of sync. This can have disastrous consequences and can result in excessive damage to the valve train.
The Fuji Billet Timing Belt Guide is a direct replacement for the existing much frailer, thinner guide (found on the EJ series from the factory).
It has been specifically designed to closely hug the timing belt and provides a much sterner buffer should the timing belt attempt to jump away from the toothed crank pulley.
