Flywheel Bolt Kit - BMW 2.3L S14

The ARP Flywheel Bolt Kit for BMW 2.3L S14 engines is a precision-engineered fastener set designed for critical rotating assembly applications where reliability and load-bearing integrity are non-negotiable. Originally developed for high-performance and racing environments, this bolt kit serves both OEM replacement and performance upgrade needs across BMW S14 platforms. Built to ARP's exacting standards, each bolt in this set of eight delivers the clamping force and fatigue resistance required to secure the flywheel under extreme operating conditions.

Each bolt measures 12 mm x 1.50 thread pitch with a 0.870-inch length and features a 12-point head geometry that ensures even stress distribution and positive engagement with ARP's matching socket. Manufactured from chromoly steel and finished with black oxide coating, these bolts resist corrosion while maintaining tensile strength across thermal cycling and high-RPM operation. The black oxide finish protects against oxidation and provides a clean, professional appearance. Chromoly's superior fatigue resistance compared to standard fasteners makes this kit essential for any S14 build where flywheel security cannot be compromised.

This flywheel bolt kit is ideal for BMW S14 engine builders, performance technicians, and enthusiasts performing engine assembly or rebuilds where original fasteners show wear or damage. Installation requires proper torque specifications (refer to BMW service documentation) and use of ARP's proprietary assembly lube to achieve correct preload. The set of eight bolts covers a complete flywheel fastening application on the 2.3L S14, making it a direct replacement solution that restores OEM-equivalent or enhanced holding capacity. Compatibility is limited to BMW 2.3L S14 platforms; verify your engine code before ordering.
