Stop dangerous hydraulic drift and eliminate fluid leaks with this premium Replacement Hydraulic Cylinder Seal Kit (Part # 2901322). Engineered specifically for heavy-duty JLG Articulating Boom Lifts, this precision-machined rebuild kit includes every high-pressure O-ring, wiper, and urethane seal required to completely overhaul your lower lift cylinder.
A weeping hydraulic cylinder is a massive safety and OSHA liability. If your lift cylinder seals are degraded, the boom will slowly drift downward under heavy load, severely endangering operators in the basket. Don't pay outrageous $315+ dealership markups or buy cheap, unverified overseas rubber that will blow out under maximum PSI. Our aftermarket JLG seal kits are manufactured to exact OEM pressure tolerances, featuring heavy-duty wipers designed to scrape away job site mud, ice, and cement dust before it destroys your cylinder rod. We offer transparent wholesale pricing to get your aerial equipment lifting safely and holding pressure perfectly.

Expert Tip: When rebuilding a JLG lower lift cylinder, it is absolutely critical to inspect the chrome cylinder rod for deep vertical scratches, pits, or rust before installing the new seals! If the rod is damaged, it will instantly tear the new high-pressure lip seal the first time the boom is raised. Always assemble hydraulic seals using clean hydraulic fluid—never install them dry!
