Dial gauge from ARP for measuring the connecting rod bolts during assembly
The tightening torque for ARP connecting rod bolts is secondary. The stretching of the expansion bolt is more important. The elongation can be accurately determined with the APR dial gauge. With the adjustable stop, the ARP dial gauge can be used for all common expansion bolts. Please ensure that sufficient ARP Ultra Torque Paste is always used when assembling and tightening the screws.
