Good To Know

Q: Will this seal kit fix a slow-dropping loader arm? A: Yes, if the cylinder is leaking internally, this kit replaces the worn seals that cause the arm to drift down under load.

Q: Are there any special tools needed for installation? A: Basic hand tools and a seal installer or pick are typically sufficient, and careful cleaning of the cylinder bore before assembly is essential.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
