Hydraulic cylinders power the heavy lifting in RV leveling jacks, slide-out mechanisms, and other hydraulic systems. When a cylinder develops internal leaks, loses seals, or becomes damaged, replacing or rebuilding it restores proper system function. We carry replacement cylinders for Lippert and other common RV hydraulic systems, sized to match original equipment specifications.

What to Know Before You Buy

• Cylinder specifications include bore diameter, stroke length, and mounting configuration—all must match your original equipment.
• Identify your system manufacturer and model number for the most accurate cylinder matching.
• Some cylinders can be rebuilt with seal kits; others are replacement-only units.
• Hydraulic fluid must be compatible with your system's seals and the replacement cylinder's specifications.

When it comes to enhancing your RV experience, we understand the importance of reliable RV parts and accessories. That's why we recommend Lippert Hydraulic Cylinders available at RVupgrades. These cylinders are engineered for strength and durability, ensuring that your RV's slide-outs and leveling systems operate smoothly.

For RVs with slide-out rooms, hydraulic cylinders are essential for efficient system actuation. Many camping enthusiasts prefer hydraulic models over electric ones due to their faster and smoother operation, making them ideal for RVs with multiple slide systems.

You can count on the efficiency of Lippert's products, designed to withstand the rigors of the road. With user-friendly installation, these RV hydraulic cylinders make upgrades straightforward, allowing you to enjoy a hassle-free camping experience. In addition, their robust construction means fewer maintenance concerns, giving you peace of mind on your travels.

Slide-out systems typically utilize one to four cylinders. If you suspect a cylinder is worn out, start by testing each one individually with the slide-outs retracted to identify the faulty unit.

Once you've pinpointed the cylinder that needs replacement, fully extend all slide-outs and mark the exact position of the Nylock nut. Remove it from the piston rod's threaded section, then retract the cylinder you wish to replace. Detach the extend fitting (with the hose still connected) and attach it to the extend port of the new cylinder.

Next, extend the old cylinder again, remove the retract fitting with the hose, and attach it to the retract port of the new unit. Replace the Nylock nut in the same position as the original.
