Discount Parts Direct RV Stabilizer Jacks Set of 4 — Aluminum 11"–17" Adjustable, 7,500 lb Each with Rubber Pads

When your RV is parked and leveled, unwanted sway and floor bounce can still make movement inside the unit feel unstable. This four-pack of adjustable aluminum stabilizer jacks helps lock the frame in place for steadier walking, cooking and sleeping without replacing leveling systems or lifting the vehicle. Each jack is rated for steadying support, not for lifting tires or performing mechanical repairs.

How do these jacks stop RV rocking and interior bounce?

The jacks press firmly against the frame to reduce lateral sway and minimize floor vibration. Because they are intended for stabilization only, they work best after the RV has been leveled with your primary leveling system.

• Four-point support targets side-to-side movement and floor bounce.
• Rubber pads reduce metal-to-metal noise and absorb small vibrations.
• Firm contact prevents the frame from shifting during everyday activities.

What are the size, adjustment range, and setup steps?

Each aluminum jack adjusts with a smooth screw-style T-handle from 11 inches to 17 inches, making them suitable for many low-clearance campers and trailers. Setup is tool-free: position under a solid frame point, turn the T-handle until snug, and avoid over-tightening.

• Adjustable height: 11" to 17" per jack for flexible placement.
• Quick T-handle operation for easy campsite deployment.
• Use base plates, jack pads or wood blocks when ground is soft or uneven.

What load capacity and usage limits should I know?

Each stabilizer jack has a rated capacity of 7,500 pounds, designed to stabilize rather than lift. They are not a substitute for true lifting jacks, hydraulic leveling systems, or tire-changing equipment.

• 7500 lb rated support per jack for stabilization purposes only.
• Not designed for vehicle lifting, maintenance, or emergency towing.
• Follow manufacturer guidance: do not use as a replacement for built-in leveling systems.

How do these jacks perform on different campsite surfaces?

The compact aluminum bases and included rubber pads work across asphalt, gravel, dirt and grassy sites, but additional base plates or wood blocks are recommended on soft ground to prevent sinking. The lightweight construction makes them easy to carry and store when not in use.

• Rubber pads help protect frames and cut down on rattling.
• Use pads or plates for stability on soft or hot surfaces.
• Compact size stores conveniently in compartments or a pickup bed.

Who is this for: These Discount Parts Direct stabilizer jacks are aimed at weekend RVers, seasonal campers, and owners of low-clearance travel trailers, pop-up campers and small fifth wheels who want quick, tool-free stabilization after leveling. Choose these if you need portable, heavy-duty stabilizers for campsite comfort and interior steadiness — but not for lifting or major repairs.
