Swellisher Fifth Wheel Tripod Stabilizer — Adjustable 35–55" Height, 5,000 lb Heavy‑Duty RV Jack

This tripod-style stabilizer is built from rust-resistant steel and designed to fit most standard 5th wheel king pins. With a telescoping shaft that adjusts from 35 to 55 inches and a 5,000-pound rated capacity, the unit reduces rocking and vibration inside the trailer. It ships partly assembled so you can position and fine-tune it in roughly ten minutes with the included instructions and hardware.

How does this stabilizer reduce trailer movement?

The tripod creates a stable, triangular support under the king pin to limit lateral and fore-aft motion. By transferring load into the ground through three legs, it dramatically reduces trailer rocking and internal vibration when people move inside or in windy conditions.

• Three-legged design disperses forces for better steadiness.
• 5000 lb load rating handles most 5th wheel static loads.
• Rubber foot pads (or optional feet) increase traction on varied surfaces.

Will it fit my 5th wheel and how do I adjust the height?

Swellisher's tripod fits most common king pin sizes and trailer types; the central tube telescopes so you can match trailer geometry. Height is adjusted with a locking pin system and fine-tuned with a hand crank or collar depending on the model shipped.

• Telescoping height range: 35" to 55" to accommodate different trailer pitches.
• Locking pins secure the desired height for safe, vibration-free support.
• Parts pre-assembled—final adjustment typically takes about 10 minutes.

How durable is the stabilizer in outdoor conditions?

The tripod is made from heavy-gauge steel with a weather-resistant finish to stand up to campground and storage conditions. Welds and hardware are selected for load-bearing strength, and the protective coating limits corrosion over seasons of use.

• High-quality steel construction resists bending under rated load.
• Weatherproof finish slows rust for longer service life.
• Replaceable components and simple bolts make maintenance straightforward.

Is it easy to install and transport?

The unit arrives partially assembled so positioning under the king pin is quick; most users complete setup with basic hand tools. The tripod is also light enough to carry for typical RV storage or campsite work, and it disassembles compactly for stowing when not in use.

• Quick, tool-minimal setup—about 10 minutes from box to use.
• Breaks down for compact storage in compartments or garage space.
• Included instruction booklet and necessary fasteners simplify installation.

Who this is for: Owners of 5th wheel trailers who want a dependable, portable solution to reduce sway and interior vibration while parked. It's suited to full-time RVers, weekend campers, and anyone placing a 5th wheel in long-term storage who needs a durable, easy-to-set-up support that fits most standard king pins.
