The Kwikee Level Best 3000 is one of the most capable hydraulic leveling systems ever installed on a Class A motorhome — but when a jack fails, finding a proper hydraulic repair shop that truly understands these units is nearly impossible. That's where Mercury Hydraulics comes in.
What Is the Kwikee Level Best 3000?
The Kwikee Level Best 3000 is a hydraulic leveling system found on many Class A motorhomes manufactured throughout the late 1990s and 2000s — particularly Winnebago, Itasca, and other premium coach brands. Unlike the newer electric-over-hydraulic systems, the Level Best 3000 uses a central hydraulic pump and reservoir to extend and retract individual jack cylinders at each corner of the coach.
Each jack is a hydraulic cylinder that receives pressurized fluid from the central pump through dedicated hydraulic lines. This design delivers tremendous lifting force — enough to fully level a 40-foot Class A motorhome on uneven terrain — and when properly maintained, these systems are extraordinarily durable.
The problem is that Kwikee (now part of Lippert Components) no longer manufactures direct hydraulic replacement jacks for the Level Best 3000 system. The "replacement" jacks sold by major retailers are electric units that are not true hydraulic replacements — they require bypassing the entire hydraulic system. For owners who want to preserve their original system, or for coaches where the hydraulic pump and manifold are still in good condition, a proper hydraulic jack repair or custom-built replacement is the right answer.
The Most Common Kwikee Level Best 3000 Problems
After decades of repairing these jacks from RV owners and service shops across the country, our technicians have seen every failure mode the Level Best 3000 can produce. The most common issues we repair include:
The most common issue — worn or hardened internal seals allow fluid to bypass, causing the jack to slowly retract under load or leak fluid down the leg. This is a straightforward seal replacement job that we perform routinely.
When jacks extend very slowly or fail to lift the coach, the cause is usually internal wear in the cylinder bore, a failing seal pack, or contaminated hydraulic fluid. We inspect, measure, and restore the bore to proper tolerances.
If the coach slowly settles after leveling, the internal check valve or seal is bypassing fluid under load. This is a safety issue that must be addressed — a drifting jack can allow the coach to shift while parked.
Ground impact, overextension, or driving away with a jack partially deployed can bend the chrome-plated rod. We straighten, re-chrome, or replace rods as needed.
Years of exposure to road salt, moisture, and UV damage can corrode the cylinder body. We assess whether the damage is cosmetic or structural and repair accordingly.
Our Repair Process
When your Kwikee Level Best 3000 jack arrives at our Melbourne, Florida facility, our technicians begin with a complete teardown and inspection. Every component is measured and evaluated — bore diameter, rod straightness, seal groove condition, chrome plating integrity, and end cap threads.
We re-hone the cylinder bore to restore the proper surface finish and dimensional tolerance. Worn or damaged chrome rods are either reground to remove pitting and restore the surface, or replaced entirely. All internal seals are replaced with premium-quality seal kits matched to the original specifications. The cylinder is then reassembled, pressure-tested, and inspected for leaks before shipping.
Most repairs are completed within 3 business days of receiving the jack. We ship nationwide and provide a written report with every repaired unit.
Custom-Built Replacement Jacks
In cases where a jack is too damaged to repair — severely bent rods, cracked cylinder bodies, or stripped end caps — Mercury Hydraulics can manufacture a custom replacement jack built to the exact specifications of your original Kwikee Level Best 3000 unit.
Our custom-built replacement jacks are manufactured from high-quality steel, feature the correct bore diameter, stroke length, port locations, and mounting configuration to bolt directly into your existing system without modification. They are pressure-tested to the same standards as our repairs and include all necessary fittings.
This is the only true hydraulic replacement option available for the Level Best 3000 system — and it preserves your original hydraulic pump, manifold, and control system, which are typically in excellent condition even when a jack has failed.
How to Ship Your Jacks to Us
Removing a Kwikee Level Best 3000 jack for shipping is straightforward. Disconnect the hydraulic lines at the jack (cap the lines and ports to prevent fluid loss), remove the four mounting bolts, and the jack slides out. Most RV owners and service shops can complete this in under 30 minutes per jack.
Pack the jack securely — we recommend wrapping the rod with foam or cardboard to protect the chrome surface during shipping. Ship to our Melbourne, Florida facility via UPS, FedEx, or freight. Call us first so we can log your unit into our system and give you an estimated turnaround.
Why RV Shops Across the Country Choose Mercury Hydraulics
Most hydraulic repair shops have never seen a Kwikee Level Best 3000 jack. The combination of specific bore dimensions, stroke length, and port configuration requires experience with this particular unit. Mercury Hydraulics has repaired hundreds of these jacks for RV owners and service shops from Florida to California and everywhere in between.
RV dealerships and service centers that don't have an in-house hydraulic shop regularly ship their customers' jacks to us. We provide fast turnaround, clear communication, and written documentation with every repair — so shops can keep their customers informed and get coaches back on the road quickly.
