Cylinder liner kits are used to repair engines with damaged or worn cylinder bores. The old bore is machined out, and a new, durable sleeve is pressed in, effectively creating a new cylinder surface. This process restores compression and oil control without replacing the entire engine block. ECT AutoCore Trading supplies high-quality cylinder liner kits for common engine rebuilds. Our liners are made from wear-resistant cast iron and are precision-machined to ensure perfect bore diameter, surface finish, and secure fit, providing a cost-effective solution for major engine restoration.
