Description
The harmonic balancer is one of the most critical fastening points on your engine—it handles extreme rotational forces that can shear inferior bolts under high RPM conditions. ARP’s 134-2501 SBC Balancer Bolt Kit delivers the clamping force and material integrity needed to keep your balancer secure, whether you’re running a stock engine or a heavily modified small block. These chromoly bolts eliminate the risk of balancer slip and potential catastrophic engine damage.
