This high‑quality aftermarket hydraulic arm (stick) cylinder (Part No. KBV0822) is a direct OEM replacement for the Link‑Belt 3400Q (Quantum) excavator. As the core component controlling arm extension/retraction, it delivers strong, stable power for digging, trenching, and material handling. Designed for medium‑to‑heavy duty applications—including earthmoving, quarrying, and road construction—it matches the original part’s mounting points, hydraulic ports, and performance specs for bolt‑on installation and reliable service.
