• Installs between the crankshaft flange and flexplate/flywheel
• Uses factory-length bolts for installation—no special hardware required
• Precision-machined for proper counterbalancing and vibration control

This counter balance plate is particularly useful when swapping between different crankshaft configurations or when building a custom engine combination. The straightforward installation process makes it accessible for both professional engine builders and experienced DIY mechanics working on performance builds or restoration projects.
