The Cummins OEM Cylinder Liner (3801826 / 3055099) is a high-precision wet-type sleeve engineered for direct installation into the engine block. Manufactured to strict factory tolerances with advanced surface treatments, this liner provides superior bore roundness, excellent oil retention, and maximum resistance to scuffing and corrosion during extended heavy-load operation.
