AMS Cam Gear Wrench for 08+ EJ257 Exhaust AVCS

This cam gear wrench was designed to aid in the removal and replacement of the AVCS exhaust cam gears on your 2.5L EJ257 engine. This is done by holding the gear in place while loosening or torqueing the center bolt. Clamping the timing belt in order to remove the center bolts from your cam gears can damage or weaken the belt or other engine parts. A slot for a 1/2″ ratchet or breaker bar has also been incorporated into the design to ensure you have all the torque necessary to get the job done with ease.
