ARP Harmonic Damper Bolt Set For BMW S58 Engine

The ARP Harmonic Damper Bolt Set for the BMW S58 engine is a critical reliability upgrade for high-performance and tuned applications. Designed to replace the factory torque-to-yield harmonic balancer bolts, this premium hardware kit delivers significantly improved clamping force, consistency and durability, helping to secure the crankshaft damper under extreme engine loads. ARP's precision-manufactured fasteners are trusted throughout the motorsport industry and are an essential upgrade for enthusiasts pushing the limits of the S58 platform.

BMW's factory harmonic damper bolts are single-use, grade 10 torque-to-yield fasteners that are suitable for standard power levels. However, as power and torque increase through tuning, upgraded turbochargers or ethanol fuel systems, the factory hardware can become a weak point. Upgraded ARP hardware provides repeatable clamping loads and superior fastener strength, helping to reduce the risk of bolt loosening, damper movement and potential crankshaft damage.
