ARP 234-2501 Small Block Chevy Harmonic Balancer Bolt Kit – 7/16-20 Thread Chromoly Fastener with Washer

Description

The ARP 234-2501 Harmonic Balancer Bolt Kit is engineered for Small Block Chevrolet engines requiring superior crankshaft damper retention. The kit includes a high-strength chromoly bolt with 7/16-20 threads, 2.470-inch under-head length, hardened washer, and ARP’s signature 12-point head design for improved socket engagement. || Harmonic balancers absorb significant crankshaft vibration and torsional loads, making secure fastening critical in both street and racing applications. ARP manufactures this bolt using premium materials capable of handling extreme clamping forces while helping prevent loosening under high RPM operation. || The included wide-area hardened washer improves load distribution across the balancer surface and contributes to more accurate torque readings during installation. For performance engine builders, restorers, and racers, the 234-2501 kit offers a proven fastening upgrade over standard replacement hardware.
