Features and Benefits:Revolutionary leg design pulls on the backside of the pulley;Designed for GM 3.6L Camaro, Ford;Mustang Coyote and other engines;Geometry increases the bite of the leg-to-pulley as it is tightened;Compact design accomodates tight spaces inside most engine compartments;Right tool for the right job will easily save a half hour each time it is used;Our engineers have redeveloped the legs on this Harmonic Damper Pully Puller kit, signficantly increasing the versatility and range of engines and applications. This signifcant redesign has led Schley to file multiple provisional patents. In addition to removing the harmonic damper pulleys used on the GM Chevrolet Camaro 3.6L engine, the updated and redesigned legs enable it to remove the smaller harmonic balancer equipped on the 2018 Ford Mustang Coyote engines, as well as other engines. The patent-pending legs have the correct geometry and work with the wider range of engines and pully applications because the leg is designed to pull from behind the spoke instead of the small landing pads. This feature increases the applications to many types of engines.
