Cam Sprocket Bolt Kit - BMW Mini Cooper

The ARP Camshaft Gear Bolt Kit for BMW Mini Cooper (MPN 206-1001) is a precision-engineered fastening solution designed for high-performance engine builds where camshaft timing integrity cannot be compromised. This Pro Series bolt kit features 12mm × 1.50 thread specifications and delivers the chromoly strength required for applications demanding reliability under sustained RPM and thermal cycling. The 2.085-inch length and 19mm 12-point head geometry ensure proper engagement with OEM and aftermarket cam gear assemblies while the black oxide finish resists corrosion in demanding engine bay environments.

Built from chromoly steel, these camshaft bolts offer superior tensile strength compared to standard hardware, critical for preventing gear slip during high-load conditions common in tuned Mini Cooper powerplants. The 12-point head design distributes clamping load more evenly across the fastener, reducing stress concentration at the bolt-to-head interface. Black oxide coating provides baseline corrosion resistance suitable for engine compartment exposure. Each bolt is engineered to ARP's standards for fastener consistency and reliability. The specific 2.085-inch length has been validated for proper installation depth in Mini Cooper camshaft applications without interference with adjacent engine components.

This kit addresses the needs of enthusiasts rebuilding or upgrading Mini Cooper timing systems who require OEM-compatible geometry with upgraded material properties. Whether performing a stock refresh or integrating performance cam profiles, proper camshaft fastening is non-negotiable—loose timing bolts can result in complete engine failure. The Pro Series designation indicates this kit meets ARP's enhanced specifications for critical applications. Buyers performing their own engine work benefit from having fasteners engineered specifically for the Mini Cooper platform rather than relying on generic hardware alternatives.
