ARP Stretch Gauge

Starting with a precise measurement of 0.001 inches, this ARP stretch gauge is built for engine builders who need to get their critical fasteners set just right. When you're assembling an engine, especially a performance build, getting the correct clamping force on your main caps, connecting rods, and cylinder heads is crucial. Using a stretch gauge like this one allows you to measure the actual elongation of the bolt, which is a more accurate way to achieve the target torque than just using a torque wrench alone. This method ensures your components are held together with the exact pressure specified by the manufacturer, preventing issues like bearing spin or head gasket leaks.

This tool is well-made from durable materials, designed to withstand regular use in a shop environment. Its clear markings and comfortable grip make it easy to handle, even when you're working in tight spaces. ARP is a well-known name for engine fasteners, and this stretch gauge reflects their commitment to providing the tools needed for a solid engine build. It’s a practical addition to any mechanic’s or serious DIYer’s toolbox when precision is the top priority.
