ARP Connecting Rod Bolts are a highly recommended upgrade for the BMW S65 engine (E90/E92/E93 M3), offering a substantial increase in strength and reliability over the factory hardware. The OE bolts are known to stretch under high RPM and sustained load, especially on track-driven cars. ARP’s ultra-high-tensile fasteners provide far greater clamping force, exceptional fatigue resistance, and consistent performance where it matters most.

Whether replacing rod bearings, rebuilding an engine, or simply carrying out preventative maintenance, ARP rod bolts are considered essential for safeguarding the S65’s bottom end. Manufactured from ARP2000 alloy and engineered to precise tolerances, they deliver the durability and peace of mind required for both spirited road use and demanding track environments.
