Cylinders are constructed from premium aluminum castings with cast-in iron liners
Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
Black or silver powder-coat finish
Made in the U.S.A.
NOTE: This project requires a skilled technician. It is the responsibility of the person assembling the parts to check all clearances and assembly specifications.
