Our cylinder liners have long been regarded as "the heart of the engine" – providing a strong, long wearing cylindrical structure that allows the piston/ring set to retain high compression and lubricity throughout millions and millions of cycles. By the unique design configuration and metallurgical specification, each liner provides a reliable surface that withstands the temperature, pressure and frictional forces that are created in the engine to develop maximum horsepower and torque. Slinger liners and pistons are made to compliment each engine design and deliver years of reliable service.
