5,000 lb RV Stabilizer Jacks, 20-47.5" - Standard 2 Pack

Heavy-duty RV stabilizer jack set designed to support slide-out rooms, reduce movement, and help steady parked RVs, travel trailers, and 5th wheels. These are support/stabilizing jacks only and are not designed for lifting a vehicle or changing tires.

Part Number: RVS-829261 2-Pack With Crank Handle 20" to 47.5" Adjustable Height

Overview

This DUMBLE RV Supplies 2-pack stabilizer jack set is built for parked RV, camper, travel trailer, and 5th wheel support applications where extra stability is needed under a slide-out room or frame support point. The telescoping design adjusts from 20 inches to 47.5 inches, while the threaded top screw allows fine pressure adjustment using the included manual crank handle.

R&P Service Insight

Slide-out rooms can place extra load and leverage on an RV structure when extended for long periods. Proper support helps reduce strain, flex, rocking, and unwanted movement while the unit is parked.

  • Slide-Out Support: Designed to help support extended slide-out rooms on RVs, campers, travel trailers, and 5th wheels.
  • Stability Control: Helps reduce rocking, swaying, and flexing motion while the trailer or RV is parked.
  • Important Safety Limit: These jacks are not for lifting the RV, raising wheels off the ground, or changing tires.

R&P Knowledge Hub

Compatibility: Suitable for RV, camper, travel trailer, and 5th wheel stabilizing/support applications where the 20" to 47.5" height range matches the needed support point.

Vehicle / System Fit: Commonly used under slide-out rooms or approved structural support points to reduce frame strain and movement while parked.

Installation Notes: Position the jack on firm, stable ground and align it with a proper support point. Do not use these jacks as lifting devices.

Performance Insight: The wide circular footpad helps spread load at the base, while the telescoping body and screw adjustment allow coarse and fine height control.

Brand & Fitment Note

Selling Brand: DUMBLE RV Supplies

Application Reference: RV, travel trailer, camper, and 5th wheel references describe general stabilizing and slide-out support applications only.

What This Means: This listing is for a DUMBLE RV Supplies 2-pack stabilizer jack set with one manual crank handle.

Before Ordering: Verify the required support height, ground clearance, support location, and intended use before installation. These jacks are for stabilization/support only, not vehicle lifting.

R&P Repair Insight

Stabilizer jacks are often misunderstood as lifting jacks. For RV and trailer use, they should be used to support and steady an already parked and properly leveled unit, not to carry the full lifting load of the vehicle.

  • Check the Height Range: Confirm the 20" to 47.5" adjustment range fits the distance between the ground and your slide-out or support point.
  • Use the Right Contact Point: Place only against approved structural support areas. Avoid thin panels, trim, plumbing, wiring, or unsupported flooring.
  • Support, Don’t Lift: Apply only enough pressure to stabilize the RV or slide-out. Do not jack the RV upward or lift wheels off the ground.
