Overview

When your crankshaft is flexing under high-RPM punishment, you need hardware you can trust. ARP balancer bolts are purpose-built to keep your harmonic balancer locked down tight, lap after lap.

Each bolt is crafted from heat-treated 8740 chromoly steel, offering a beefy 200,000 psi tensile strength for serious clamping force. The square drive head design provides a secure grip during installation—no drama, no stripped heads, just rock-solid engagement.

If you’re chasing durability and performance, this ARP balancer bolt is the upgrade your build deserves.
