S&S® racing cylinders are designed to withstand the punishment of today's more powerful engines, giving racers a competitive edge with a high degree of safety. S&S racing cylinders are sold in pairs, and do not include pistons, hardware or gaskets. These items must be purchased separately. A number of cylinder bore sizes are available. For each bore size there are a number of head and base bolt patterns that may be used. S&S is familiar with most commonly used bolt patterns, however, if a different pattern is specified, or if we are unsure of the pattern specified, a print of the pattern must be supplied.
Finless Steel Racing Cylinders
- Machined from 4142 chromoly steel—180,000 psi approx. tensile strength—a higher strength to weight ratio than that of competitive cast iron racing cylinders
- Replaceable sleeve made of ductile iron (superior wear resistance) allows worn or damaged cylinders to be rebuilt and reused
Finned Aluminum Racing Cylinders
- Developed for the S&S Pro Stock engines, but can be used in many other gasoline racing applications
- Machined from solid aluminum billets for maximum strength and improved heat dissipation
- Replaceable sleeve made of ductile iron (superior wear resistance) allows worn or damaged cylinders to be rebuilt and reused

NOTE:S&S finned aluminum racing cylinders are intended for gasoline engines only and are not recommended for nitromethane powered engines.
