Advantage

Our Hitachi-style hydraulic cylinders are designed for real jobsite challenges—not just the specs on paper. Whether you're digging, lifting, or breaking through tough terrain, they offer the kind of reliability and wear resistance that keeps machines running longer without surprises.

Simple Fit, Faster Turnaround:
No need for modifications. These cylinders fit directly onto Hitachi excavators, making installation quick and straightforward. The result? Less time in the workshop, more time in the field.

Materials That Last:
We use high-grade steel, precision machining, and top-tier seals to ensure each cylinder stands up to fatigue, pressure, and harsh environments. It’s the kind of durability you’ll notice in fewer breakdowns and longer intervals between maintenance.

Responsive Where It Counts:
Expect smooth, controlled movement of your boom, arm, and bucket—even under load. These cylinders deliver the responsiveness operators need to handle both heavy lifting and fine movements with confidence.

Works Where You Work:
From road construction to foundation work and everything in between, these cylinders are built for versatile performance. Whatever the job, you’ll have the control and power to get it done right.
