Title:

Kubota Boom Cylinder Assembly

Description:

The Kubota RG158-67500 Boom Cylinder Assembly is a complete hydraulic actuator responsible for raising and lowering the boom on Kubota compact excavators. It converts hydraulic pressure into linear motion, delivering the lifting and lowering force required for digging, grading, and material handling operations.

This cylinder assembly includes the honed barrel, precision-machined piston rod, piston, gland, seals, and fittings—all factory-assembled and tested by Kubota to ensure leak-free, high-efficiency performance. It’s engineered for smooth hydraulic response, high load capacity, and durability under demanding working conditions.

The RG158-67500 is an OEM direct-fit replacement, ensuring compatibility with the machine’s hydraulic system, mountings, and control geometry. It restores original digging force, motion smoothness, and reliability in daily operation.
