Is this worth it over rebuilding my old cylinder?

If your cylinder is pitted or the rod is bent, a rebuild will not last. A new Lippert LC339031 is the safer fix. If only the seals are worn, a seal kit is much cheaper.

It fits Lippert hydraulic slide systems, including RVs with multiple slide rooms. Match the 24 inch stroke and 1-1/2 inch bore to your old cylinder, and check the part number on the label before ordering.

You get the cylinder itself. Hoses, fittings, mounting hardware and hydraulic fluid are usually sold separately, so plan on reusing or replacing those.

How hard is the install?

It is a moderate DIY job. You disconnect the lines, swap the cylinder, refill and bleed the system, then check slide alignment. A dealer install runs a few hours of labor.

Prices swing by seller and stock. Compare listings for LC339031 across stores and buy when a seller drops below the usual range rather than at the first price you see.

Our take on the Lippert Replacement Hydraulic Cylinder for RV Slide-Out

This is a replacement hydraulic cylinder for Lippert RV slide-out systems, part number LC339031. It has a 1-1/2 inch bore, a 24 inch stroke and a 4,500 lb load rating, and it fits RVs with multiple slide rooms on a Lippert hydraulic system. It is an aluminum-bodied cylinder about 39 inches long and weighs roughly 7 pounds. It is a repair part, so it is worth pricing against a full Lippert cylinder assembly and a shop rebuild before you buy.
