n this category you will find all the components for overhauling hydraulic cylinders not present in the categories below. Then the pistons, i.e. the part where the oil that arrives under pressure pushes, as well as the chrome rods, i.e. the component of the cylinder that stretches and retracts. You will find the cylinder heads as well as the extensions. The latter are screwed onto the tilt cylinders to make them suitable for multiple uses depending on the characteristics of the tail lift and especially the length of the lifting arms.
