Description
BMW OEM damper bolts are grade 10 and Torque to Yield, designed for one-time use. While this is adequate for factory power levels, these bolts fall short when power levels are increased. 5150 AutoSport has observed damper bolts coming loose and breaking, leading to engine and crank damage, as well as improper torque load between bolts. The factory bolts are simply not sufficient for those planning to run above factory power levels.
5150 AutoSport proudly offers a solution with the ARP Harmonic Damper Bolt Set for BMW S58 Engines. These bolts are made in the USA to ARP’s exacting standards, ensuring each bolt provides even, repeatable torque load as designed. ARP Hardware is known industry-wide for their quality and performance, making these bolts a reliable choice for enhanced power applications.
