Harley Davidson Flathead ULH - 13 Fin - Cylinders - 74" & 80"

Product Detail:

We have commissioned a limited production run of reproduction 1937 - 1948 13 Fin ULH Cylinders in both 74" & 80" sizes.  The molds were specified and approved by Paul.  If you are not familiar with Paul, he holds multiple Land Speed records at the Bonneville Salt Flats, including the fastest vintage motorcycle to ever run at Bonneville a 1937 Turbo-charged Flathead Harley at 180.659 m.p.h.  These are the same cylinders he runs in his Bonneville racing program.  These cylinders are by far the best reproduction Paul has seen.  Similar cylinders have been available in the past, but have sold out quickly.  This is likely the last time Big Twin Flathead cylinders will be reproduced. We can say for certain this is a one time offering from A.C.F.  Don't miss your opportunity to purchase these now.  As the supply dwindles down, the prices will likely rise.
Bare Cylinders - Inspected by A.C.F. for quality, finishing will require:
Final Honing to piston size - Final reaming of guides - Light cleaning of ports.
