Harmonic Balancer Bolt
Rated at 200,000 psi, our harmonic balancer bolt will securely keep your balancer intact on the crankshaft. Our balancer bolts are made from high-strength 8740 chrome-moly steel and wrapped in a corrosion-resistant black oxide finish. Our washers are extra-thickened to distribute load evenly.
Our extra tall 12 point head design ensures maximum socket contact, preventing stripping through the install and torquing process.
