Summit Racing™ Harmonic Balancer Wrenches

3.12 out of 5 stars 33 Customer Reviews

Our Summit Racing™ harmonic balancer wrenches rotate the crankshaft the proper way when turning the engine with the balancer installed. The cold-rolled steel adapter easily attaches to most balancers and comes in handy when assembling an engine or degreeing a cam. These wrenches require a 3/8 in. or 1/2 in. ratchet or breaker bar to rotate the engine.
