Product Overview

The piston ring kit 4309114 is a vital internal‑engine component designed for cumm-ins L9.3 diesel engines. It forms a tight seal between the piston and cylinder wall, preventing combustion gas leakage into the crankcase, controlling oil consumption, and transferring heat from the piston to the cylinder liner. Replacing worn‑out piston rings can effectively solve common problems such as engine power drop, excessive oil burning, blue exhaust smoke and low compression. This aftermarket replacement kit is ideal for engine repair, maintenance and full overhaul for excavators, heavy‑duty trucks and construction machinery.
