ARP Connecting Rod Bolt Kit for BMW M3 S65 4.0 V8 (E90 E92 E93) - Conrod/Big-End/Rod Cap Bolts, S65B40 Bottom-End Fasteners for Bearing Shell Service, Engine Rebuilds & Track Prep

BMW M3 V8 S65 Big-End Fastener Set by ARP

Protect your S65B40 bottom end with the ARP performance rod cap bolt set. Ideal when refreshing bearing shells, preparing a track day car, or carrying out an engine overhaul, this premium fastener upgrade delivers dependable clamp load and stability at high rpm. It is genuine ARP hardware that our team has fitted on customer cars and our own builds with excellent results and long-term reliability.

If you are building a fast-road or circuit-focused E9X M3, stronger and more consistent big-end fixings are a smart, cost-effective investment. Factory bolts can lose preload with heat cycles and age. ARP’s precision-engineered solution offers repeatable torque stretch characteristics for confidence under sustained load, giving you peace of mind when you extend the revs.

• High tensile rod cap bolts engineered for the S65 4.0 V8
• Consistent clamp force for improved bottom-end security at high engine speeds
• Perfect during bearing shell replacement, short-block refresh, or full rebuild
• Trusted by engine builders worldwide and proven by our workshop and customers
• Complete set for one engine with assembly lubricant for accurate preload
• Direct replacement for factory fasteners with performance-grade durability
