Cummins 4344299 Cylinder Liner for QSK23 Series

Precision-machined cylinder sleeve delivering optimal piston clearance and heat dissipation for the powerful 23-liter Cummins QSK23 diesel engine.

In tough environments such as mining, power generation, and heavy construction, the Cummins QSK23 engine needs reliable cylinder liners to maintain compression, control oil consumption, and handle extreme thermal cycles. The 4344299 Cylinder Liner provides the critical surface for piston movement while efficiently transferring heat to the cooling system.

Manufactured to exact Cummins specifications, this liner features a precision-honed bore for smooth piston travel, superior wear resistance, and consistent wall thickness that prevents distortion under high loads. It installs directly as a replacement, restoring factory-level performance and helping extend the time between major overhauls.
