⚙️Damper fit is one of those details that’s easy to overlook, but it matters.

Too loose, and the damper can walk on the crank snout and cause galling.
Too tight, and both surfaces can be damaged during installation, reducing contact area and damper effectiveness.

One simple trick for dual key dampers:
Fill the keyways with auto body filler before honing and let it harden overnight. It creates a smooth surface that makes honing much easier, and it pops right out afterward with a screwdriver or punch.

We also use extreme pressure l**e on both the snout and damper during install to help protect the surfaces from damage.
