Connecting rod bolts are the most critical fasteners in an engine. They function by serving to secure the link between the piston assembly and the crankshaft. A broken bolt will lead to disastrous engine failure. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. Xotic Performance connecting rod bolts are heat-treated and precisely designed to withstand fatigue. Fine threads with close pitch give maximum strength and secure tightening between the piston assembly and the crankshaft. These far exceed standard OEM fasteners in terms of durability, and they have the full potential to handle the extra stress of high-performance engines.
