Discount Parts Direct RV Stabilizer Jacks 4-Pack, 11–17 in Aluminum Stack, 7,500 lb Each

These are four aluminum stack-style RV stabilizer jacks that adjust from 11"–17" and support up to 7,500 lb each to steady a parked travel trailer or camper.

When you park for the night or set up at a campsite, unwanted sway and bounce can make moving around inside an RV awkward and noisy. Discount Parts Direct's 4-pack of aluminum stabilizer jacks is built to add rigidity to your trailer frame after you've leveled the unit. They’re designed for stabilization only—not for lifting the RV for tire changes or major repairs—and they fold down compactly for storage.

How do these stabilizer jacks reduce rocking and floor bounce?

These stack jacks provide contact points under the RV frame to limit side-to-side sway and reduce springy movement in floors. By snugging the jack until the frame is supported, you minimize the oscillation that comes from walking, cooking, or shifting weight inside.

• Point of contact: designed to sit under solid frame members
• Rubber pads reduce metal-to-frame noise when tightened
• Four jacks let you stabilize both front and rear sections of the trailer

What range and adjustment method do these jacks use?

Each jack telescopes from 11 inches to 17 inches and is adjusted with a manual T-handle screw mechanism for precise control. This low-profile travel height makes them suitable for lower-clearance trailers, pop-up campers, and many small campers—measure clearance before buying.

• 11"–17" adjustable stack design for common clearance needs
• Screw-style T-handle for tool-free, incremental tightening
• Quick setup: place, turn handle until snug, avoid over-tightening

How strong are these jacks and what are they safe to use for?

Each aluminum jack has a rated stabilization capacity of 7,500 pounds. The construction is heavy-duty for steadying parked units but they are expressly for stabilization—not for lifting the trailer for maintenance tasks like tire changes.

• 7,500 lb per jack load rating for stabilizing parked RVs
• Lightweight aluminum keeps individual jacks manageable to carry
• Not certified or intended for vehicle lifting or leveling under load

What comes with the set and how do you use them on different ground surfaces?

The kit includes four stack jacks and rubber pads to cushion frame contact and cut down on metal noise. They work on a variety of campsite surfaces when paired with wood blocks, jack pads, or base plates to spread the load and prevent sinking on soft ground.

• Four stabilizer jacks plus rubber pads included
• Use with blocks or pads on grass, dirt, gravel, or hot asphalt
• Compact for storage in RV compartments, truck beds, or garages

Who is this for: Suitable for weekend campers, seasonal RV owners, and anyone with lower-clearance trailers or pop-up campers who wants an easy, tool-free way to reduce inside motion while parked. Measure your frame-to-ground clearance before purchasing, and use these jacks only for stabilizing—not for lifting or major mechanical work.
