Our take on the Equalizer Systems 201125-30H Travel Trailer Hydra-Slide Cylinder

The Equalizer Systems 201125-30H is a hydraulic slide-out cylinder for light-duty RV room slides, with a 30-inch stroke, 1 1/8-inch bore and 3/4-inch piston rod. It uses #6 SAE O-ring boss ports and a 5/8-18 threaded rod end, and the rear cap is threaded for a 5/8-18 bolt or all-thread. It is a non-repairable basic design, so a failed seal means replacement, not a rebuild. The best new price is $700.00 at rvworkshop.com as of November 4, 2026, and only one store lists it new, so there is no price competition to compare against.

Questions and answers

Is this cylinder worth $700?
If your slide is stuck or leaking and this is the matching part, yes, because there is no rebuild kit for it. At $700.00 at rvworkshop.com as of November 4, 2026, it is the only new listing, so there is no cheaper new option to weigh.
Will it fit my RV's slide-out?
Check stroke, bore and mounting threads against your old cylinder: 30-inch stroke, 1 1/8-inch bore, 3/4-inch rod, 5/8-18 rod end and 5/8-18 threaded rear cap. Equalizer supplied this design to several RV OEMs, so match by dimensions rather than by brand alone.
Can I rebuild it instead of replacing it?
No. Equalizer lists this as a non-repairable basic design, so there are no factory seal kits. A leaking cylinder gets replaced.
What fittings do the ports take?
Both ports are #6 SAE O-ring boss, a common hydraulic size. Reuse your existing hoses if the fittings match; otherwise you need #6 ORB adapters.
What's in the box?
Expect the cylinder itself. Hoses, fittings, pins and mounting hardware are generally not included, so plan to reuse or order them separately.
When is it cheapest?
With one new listing at $700.00 as of November 4, 2026, there is no discount pattern to wait for. Watch for used or take-off cylinders if you want to spend less.
Where is the Equalizer Systems 201125-30H Travel Trailer Hydra-Slide Cylinder cheapest?
At rvworkshop.com, for $700.00, as of our latest check.
