Review on Dorman 594 309 Harmonic Balancer by Marty Wainwright

Based on my experience, I can`t recommend this particular automotive accessory... While it claims to enhance engine performance I didn't notice any significant improvement in my performance car after installing it. The installation process was also complicated and time-consuming, leading to frustration. On the positive side, the build quality seemed decent, but it didn't justify the high price tag. Overall, I would advise performance car enthusiasts to explore alternative options for engine parts..
