The ARP Stretch Gauge is designed to measure the length of connecting rod bolts , as the bolt length can change during tightening (torque). This measurement method is the most accurate and reliable way to ensure that the bolt is properly pre-loaded .

Measuring strain is a more recommended method than using torque alone, especially in performance and racing applications.

Features

• Billet aluminum construction
• Black anodized finish
• Extremely stiff springs to ensure consistent and repeatable measurement results
• Comes with a durable, insulated plastic storage case for protection
• An essential tool for the serious engine builder

More information and user manual

Always follow the bolt manufacturer's instructions .

• Measure the bolt length before installation
• Monitor the total length of the bolt during tightening

When the bolt has stretched to the amount specified by the manufacturer, the correct preload or tightening torque has been achieved .

ARP recommends keeping a record of all connecting rod bolts , noting the bolt length before and after installation.

If the bolt length has permanently increased by 0.001" (≈0.025 mm) or more or if any deformation is observed in the bolt , the bolt should be replaced immediately .

Don't take any risks – safety is the foundation of everything when it comes to critical engine components.
