Hoses, fittings, and couplers included.

Length is measured from center-of-pin to center-of-pin.

You can measure the retracted and extended length of your existing top link and compare to the options available here, or measure it as it sits with one of your implements, and put that length more or less in the center of the stroke.  

Double Pilot Check valves:

• Will hold their position even if a hose breaks or is disconnected

• Will not "float" even if valve has this feature

• Will not work with "dump" circuit using a diverter valve (due to regenerative fature of dump circuits)
