Cannonball Panhead Crankcases

Reproduction crankcases which meet or exceed highest restoration demands. Cast from state-of-the-art materials and machined on CNC equipment for strength and precise fitment. Intended to work with stock or identically constructed engine components. Finished and detailed like the original counterparts so these cases will smoothly blend into your old mill to give it a new life. For ease of installation both case halves are carefully matched and feature pre-installed case bushing which are line bored and lapped for standard rollers. Cam bushings are already in place, too, reamed to standard size.

The selection includes cases with a smooth, uniform glass bead blasted finish and cases with an NOS (new old stock) finish. The latter means the finished cases are not bead-blasted but treated in a traditional process which gives them the appearance of new factory cases that had been sitting on the shelf for 50 years. Perfect for those "patina restorations".

All cases feature laser-engraved CB production numbers, which are registered and filed.
