Product Overview
The Hyva 71907541K is the A137-4-HD heavy-duty telescopic-cylinder seal kit. It supplies the service seals for that cylinder configuration rather than a complete replacement cylinder.
The HD designation is part of the fitment. Standard A137-4 kit 71907540K is a different part number, so this kit should be selected by the cylinder designation rather than by a general 137-series description.
