987921 Rocker box alignment tool

When you are buttoning up a Twin Cam top end, getting the rocker boxes perfectly centered is crucial for a long-lasting seal. This MCS rocker box alignment tool is designed specifically for 1999 to 2017 Twin Cam models to ensure everything stays exactly where it should be during the tightening process. By preventing the boxes from shifting as you torque them down, you eliminate the risk of misalignment that often leads to annoying oil leaks down the road. It is a must-have for any serious engine build or top-end refresh. This tool is sold as a kit and corresponds to part number 987921, providing the precision needed for a professional-grade assembly every time.
