Construction & Design

The ARP Stretch Gauges are meticulously engineered with precision in mind. The gauges themselves are made from high-grade steel, providing durability and resistance to wear. The dial indicator features a smooth, responsive movement with a clear, easy-to-read scale, allowing for accurate measurement of bolt elongation during tightening. The included case is constructed from tough plastic, offering protection and portability for professional workshops or personal garages. This kit's design emphasizes ease of use, accuracy, and reliability, making it an indispensable tool for engine builders who prioritize precision and consistency.

Installation & Fitment

Using the ARP Stretch Gauges is straightforward and does not require any special tools beyond the kit itself. To measure bolt stretch, simply attach the gauge to the rod bolt, tighten the fastener to the specified torque, and observe the dial indicator for the elongation reading. This process allows you to verify that the bolt has achieved the correct stretch, ensuring proper preload. No additional modifications, cutting, or tuning are necessary. The gauges are compatible with ARP fasteners and can be used on a variety of engine configurations where bolt stretch measurement is applicable.

• Attach the gauge to the rod bolt according to the included instructions.
• Tighten the bolt to your engine's specified torque.
• Read the dial indicator to verify the bolt stretch within the recommended range.
• Repeat as needed to ensure consistent preload across all fasteners.
