The bolt is the weak point of a connecting rod, and these replace the stock ones with others that have much higher fatigue resistance.\u003c\/p\u003e\u003cp\u003eARP recommends installing them by checking the stretch, between 0.0080 and 0.0085 inches, with a reference torque of 36 lb-ft (about 49 Nm) using their lubricant. It is advisable to measure the stretch of each bolt and replace it if it has been permanently stretched by more than one thousandth of an inch.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their torque values, because with another lubricant the load each part receives is not the same.
