Discount Parts Direct RV Stabilizer Jacks 4-Pack — Aluminium Stack Jacks 11–17", 7,500 lb Capacity Each, Rubber Pads

When your RV, travel trailer, or pop-up camper is set on site, movement from walking, cooking, or wind can make the experience less comfortable. This 4-pack of aluminum stack jacks is built specifically for stabilization (not for lifting) and uses a simple screw-style T-handle for fast, tool-free setup. The compact design and included rubber pads help protect frames and quiet metal-to-metal contact while making storage and transport easy for most campers.

How do these jacks improve campsite stability?

These stack jacks reduce side-to-side sway and floor bounce by taking frame pressure off the suspension and settling the coach onto firm contact points. They are intended to be used after the RV is leveled with the primary jacks, providing supplemental support for everyday activities inside the vehicle.

• Minimizes interior movement while walking, cooking, or sleeping.
• Rubber pads reduce noise and protect frame surfaces.
• Four-point setup increases overall steadiness compared with single-point supports.

Will they fit my RV and how do I pick the right height?

Each stabilizer adjusts from 11 inches to 17 inches, making them suitable for lower-clearance travel trailers, pop-up campers, and many small campers. Measure the distance from your chosen frame contact point to the ground before buying to ensure the adjustable range covers your needs.

• Adjustable range: 11"–17" to match common frame heights.
• Screw-style T-handle lets you fine-tune contact pressure without tools.
• Not intended as a primary lifting device—use only for stabilization.

How strong and durable are these aluminum stack jacks?

Constructed from heavy-duty aluminum, each jack carries a rated capacity of 7,500 lbs for stabilization purposes. The material choice keeps individual units lightweight for handling and storage while providing robust support when placed under solid frame contact points.

• 7500 lbs rated capacity per jack for stabilization use.
• Aluminum body balances strength with reduced weight for easy handling.
• Compact footprint fits in RV compartments, garages, or truck beds.

How do I set them up safely on different ground surfaces?

The jacks include rubber pads and work well with additional boot plates, wood blocks, or jack pads to distribute load on soft or uneven ground. Place each jack under a solid part of the frame, tighten until snug, and avoid over-cranking to prevent undue frame stress.

• Use included rubber pads to lower noise and protect frame contact areas.
• Add base plates or wood under the pad on gravel, dirt, or hot asphalt.
• Do not use these jacks for tire changes, major lifting, or final leveling.
