Piston Shaft Runout Testing

A bent piston shaft may not create a leak but they can create friction and premature guide bushing wear. A bent piston shaft may not be able to be seen by the naked eye so we custom designed a piston shaft runout measuring tool to measure runout down to 0.0005".

Piston shaft runout tests do not include labor costs to remove piston shafts from the damper. The price of the test is with the piston shaft already removed.
