The Cal-Van Tools Ratcheting Harmonic Balancer Puller is designed to remove harmonic balancers without the hassle of trying to start bolts or the frustration of positioning multi-jointed puller legs. It features three ratcheting legs with puller feet to eliminate the need for bolts and a compact, patent-pending design so that there is no need to remove the radiator or other components. The legs quickly adjust and hold their position. It has a push-turn click design, enabling technicians to save time and effort. It's ideal for Ford 5.0 Coyote; GM: 5.3L, 5.7(LS1), 6.0(LS2), 6.2(LS3), and 7.0L; and most three and six spoke harmonic balancers/pulleys.
