Piston rod extensions are purchased separate from our systems. Extensions are interchangeable with the piston rods that come with our system. This means you can install the extension kit when more width is needed and take out the extension when less width is needed.
The top image on the right represents the original piston (Note: system widths vary and the width of the original piston depends on the size system you purchase).
The bottom image represents using an extension kit on the original piston rod ultimately increasing the width and allowing you to use your system for more jobs (Note: extension kit vary both in width and style).
We carry two style of extension kits. One for locking piston rods and the other for standard piston rods.
