The outer tube, mounting and foot stay on the trailer. A cylinder is the right part when the jack leaks, will not hold a load, or will not build pressure while the pump and valves test good.\u003c\/p\u003e\u003ch4\u003eCheck the fittings\u003c\/h4\u003e\u003cp\u003eOlder EQ Systems cylinders were built with NPTF fittings and current production uses SAE. On an SAE fitting there are no threads exposed between the cylinder body and the hex; on NPTF the threads are exposed. If your jack has NPTF fittings, call EQ Systems at 800-846-9659 before ordering so the correct fittings go out with the cylinder.\u003c\/p\u003e\u003ch4\u003eRelated\u003c\/h4\u003e\u003cp\u003eTJ single leg systems are run by the \u003ca href=\"\/products\/replacement-hydraulic-pump-3200ks\"\u003e3200KS\u003c\/a\u003e pump with reservoir 3333K, and take cover 70337.
