The ARP Billet Rod Bolt Stretch Gauge (100-9942) is designed for automotive mechanics and engine builders needing precise control over rod bolt clamping force. Its key benefit is ensuring accurate, repeatable rod bolt stretch, critical for engine longevity and performance. A potential caveat is that it requires a basic understanding of engine assembly principles for effective use.

A rod bolt stretch gauge measures the elongation of a connecting rod bolt, ensuring it is stretched to the precise specification required for proper clamping force. This is more accurate than relying solely on torque values, which can be influenced by friction.
By accurately setting the correct clamping force, the gauge prevents issues like rod bearing failure or bolt fatigue that can result from under- or over-stretching, thereby enhancing overall engine reliability.
No, the ARP Billet Rod Bolt Stretch Gauge (100-9942) is specifically designed for use with ARP connecting rod bolts. Compatibility with other brands or types of fasteners is not guaranteed.
The package dimensions are approximately 23.622 cm L x 10.921 cm W x 3.81 cm H.
This product is manufactured in the United States.
The package weight is approximately 0.91 lbs.
This gauge is specifically designed for connecting rod bolts. Using it for main bearing cap bolts may not provide accurate measurements due to different bolt designs and specifications.
Ensure the measuring surfaces are clean and free of debris. Check for any physical damage to the gauge.
Verify that the gauge is being applied perpendicular to the bolt and that consistent pressure is used during measurement. Ensure the bolt is clean and free of thread lubricant when measuring 'free length'.
Confirm you are using the correct gauge for the specific ARP rod bolt series. Ensure the bolt threads are clean and undamaged.
Setup: The ARP Billet Rod Bolt Stretch Gauge is designed to be used during the engine assembly process. Typically, it is utilized after the rod bolts have been partially threaded into the connecting rod. The gauge is placed onto the bolt, and the measurement is taken. The bolt is then tightened, and the stretch is measured again to achieve the desired specification (e.g., 0.005 to 0.007 inches). Always refer to the specific installation instructions provided by ARP for your connecting rod bolts, as stretch specifications can vary.
Compatibility: This gauge is specifically designed for use with ARP connecting rod bolts. While ARP offers various bolt series, this gauge is generally compatible with most ARP billet rod bolts that have a sufficient length for measurement.
Care: To maintain the accuracy and longevity of the gauge, clean it after each use with a soft, dry cloth to remove any debris or oil. Store it in a clean, dry environment, preferably in its original packaging or a protective case, to prevent damage or corrosion.
