91E6-2710 Boom Cylinder Seal Kit — Product Overview

The 91E6-2710 Boom Cylinder Seal Kit is a precision aftermarket replacement for Hyundai R130LC excavator boom cylinders. Engineered for 75mm rod and 105mm bore hydraulic cylinders, this kit matches the 91E6-2711 cylinder series and provides complete reseal coverage for the lift function on Hyundai R130 series excavators.

The boom cylinder on the Hyundai R130LC handles the primary lifting loads — raising and lowering the entire front attachment including boom, arm, and bucket during excavation and material handling. Seal failure in the boom circuit results in boom drift during stationary holding, reduced lifting capacity under load, and external hydraulic oil leakage. The 91E6-2710 kit addresses these failure modes with application-matched seal compounds.

Manufactured with high-performance polyurethane rod seals and NBR static seals etc for reliable fluid containment across the full operating temperature range of Hyundai excavators. DJF Seals supplies the 91E6-2710 at factory-direct wholesale pricing — a dedicated boom cylinder solution for the Hyundai R130LC platform.
