Proform Rod Bolt Stretch Gauge 66788

Precise rod bolt stretch measurement is critical for engine assembly—improper torque specs can lead to catastrophic failure, while accurate stretch gauging ensures repeatable, reliable clamping force across your builds. The Proform Rod Bolt Stretch Gauge eliminates guesswork by delivering dial-indicator accuracy to 0.001-inch increments, giving you the confidence that every engine you build meets OEM or race-spec standards. Whether you're assembling a street engine or prepping a competition block, this tool bridges the gap between theoretical torque values and real-world bolt behavior.
