Collection: Sleeves

A cylinder sleeve (also called cylinder liners or engine sleeves) is a cylindrical metal engine component that protects an engine’s bore and can be used to create bore dimensions after an engine has been over-bored or modified. Cylinder sleeves also assist in transferring heat from the piston to the coolant (if you are running a wet sleeve). Ductile iron is the preferred material for high-performance engine sleeve applications due to its improved tensile strength, yield strength, and elongation.
