As the crankshaft flexes, the damper absorbs incredible amounts of energy. These damper bolt kits from Speedmaster will ensure that your balancer is locked into position. They feature a 1/4 in. thick wide-area washer and an extra-tall, 12-point head that accepts a deep socket to eliminate the fear of stripping the head.
