M.A.P. Billet Cylinder Kits are fully CNC machined extrusions. Expensive 6061-T6 alloy billet extrusion, similar to a forging, is compressed and formed under extreme pressure for correct grain alignment to the shape of the largest fin, producing considerable increase in strength over normal billet material, but especially when compared to 356 castings.
Note: An "out of stock" listing does not mean your kit is unavailable. With all of our many custom cylinder configurations coupled with our special piston choices, it is impossible to have every kit finished and inventoried as on the shelf. Most cylinder versions are semifinished needing less than one to two weeks to finish! Please INQUIRE!!
