Summit Racing™ Harmonic Balancer Bolts

4.27 out of 5 stars 116 Customer Reviews

These heavy-duty Summit Racing™ balancer bolts are the best way to bolt on your damper. As the crankshaft flexes and twists, the damper absorbs a lot of kinetic energy. To ensure that the damper stays on tight, these bolts include a thicker flat washer, machined perfectly flat to spread the fastening load over a greater surface area. They're manufactured from premium materials for maximum strength and feature a quality finish for good looks.
