91E6-2711 Boom Cylinder Seal Kit — Product Overview

The 91E6-2711 Boom Cylinder Seal Kit is a precision aftermarket replacement for the Hyundai R130LC excavator. Designed for the boom cylinder with 75mm rod and 105mm bore dimensions, this kit is manufactured to Hyundai OEM specifications using premium sealing materials etc.

The boom cylinder on the 13-ton R130LC platform carries the full weight of the arm, bucket, and payload through every lift cycle. Seal integrity is critical for maintaining lifting power, preventing boom drift, and avoiding hydraulic oil leaks that compromise jobsite safety and environmental compliance. The 91E6-2711 kit uses polyurethane rod seals engineered for the lift cycles and working pressures of the R130LC, with PTFE backup rings for extrusion protection under maximum boom lift pressure.

DJF Seals supplies this kit at factory-direct wholesale pricing, serving Hyundai equipment dealers, independent repair centers, and construction fleet maintenance teams.
