When it comes to a high-performance engine, having the right harmonic balancer bolt is important. If you are still using stock or mediocre bolt, then it is time to change it to a premium and high-quality harmonic balancer bolt. Holley Harmonic Balancers, designed for a variety of Ford and Chevvy vehicles, are just what you need.

These Harmonic Balancers are made using 4135 chrome-moly steel that provides them with high strength. Sporting a black-oxide finishing that provides a higher degree of resistance to corrosion, these Harmonic Balancers have a 180,000 PSI tensile strength rating. And this helps the balancer stay at the right place all the time, which is on the crank. The extra-thick washer on these balancers allows for even load distribution. With high-quality threads, you get the most accurate torque readings with the maximum engagement of the threads.

Every harmonic balancer has a 12-point head design that provides the highest degree of socket contact on its bolt. And this provides prevention from slipping and stripping while torquing and installation. With Holley's Harmonic Balancers, you can help to avoid any engine vibration and ensure that your engine continues to provide the best performance for a long time.
