ARP's Rod Bolt Stretch Gauge provides an extremely accurate measurement when the tightening up your conrod fixings, which is always preferable to using a torque wrench.
It's been developed to provide optimum accuracy in determining the correct pre-load of the installed rod bolt.
This can also be used to monitor the condition of the bolt when installed, which is particularly useful on a race engine that's regularly apart for check-ups.
The gauge is supplied with a heavy-duty carry case and is ideal for both DIY and professional engine builders.
