S&S Cycle Twin Cam Cylinders

Not Yet Reviewed

Boost your engine's performance with S&S Cycle's Twin Cam cylinders. The design, finish and workmanship of these cylinder replacements feature many improvements over stock units, including sturdier walls that are far less prone to warpage. Straighter, sturdier walls equals a better seal, and fit for pistons, and piston rings. An improved machining process also ensures a better surface for both the head and base gaskets. These cylinders feature ductile cast-iron sleeves in aluminum castings and are offered in black wrinkle finish. Select the cylinders designed to fit your specific HD® model.
