TENFUN Trailer Stabilizer Jacks 4-Pack 11.5"–18" Telescoping Drop-Leg, 1000 lb Each, Powder-Coated Steel

TENFUN Trailer Stabilizer Jacks are a four-piece set of heavy-duty telescoping drop-leg supports that reduce RV movement and level trailers from 11.5" to 18".

Designed for travel trailers, campers and utility trailers, this complete 4-pack provides dependable corner support to minimize rocking and create a steadier living space at the campsite. Each unit telescopes for fine height adjustment, locks securely with included steel pins, and rests on a wide footplate that helps prevent sinking on soft ground. Built from powder-coated steel, the jacks resist outdoor wear while offering a simple bolt-on installation that most owners can complete with basic tools.

How much weight can each TENFUN stabilizer jack handle?

Every jack in the set is engineered for substantial static support, helping to stabilize corners of trailers and reduce motion. They are not intended as primary lifting devices for towing maintenance—use dedicated jacks for lifting tasks.

• Rated capacity: up to 1000 lbs (approx. 450 kg) per jack for stabilizing purposes.
• Four-jack set provides distributed support across the trailer’s corners.
• Designed for static stabilization rather than heavy lifting under the axle.

What height range and adjustment features do these jacks offer?

The telescoping drop-leg design gives a practical range for most campsite and driveway situations, enabling you to adapt to uneven ground and different hitch or frame clearances. A simple pin-lock system secures the selected height quickly.

• Adjustable length: 11.5" minimum to 18" maximum per jack.
• Telescoping tubing for incremental height changes and snug fit.
• Includes steel pins to lock each jack at the chosen extension.

What materials and components ensure durability and reliable contact with the ground?

These stabilizer jacks combine robust steel construction with a corrosion-resistant finish and a broad footplate to maximize ground contact and longevity. The components are sized to resist bending and provide stable purchase on grass, gravel or packed dirt.

• Heavy-gauge steel body with black powder-coat finish for weather resistance.
• Wide footplate distributes weight to reduce sinking on soft surfaces.
• Mounting brackets and hardware included for secure bolt-on installation.

How easy is installation and everyday use?

Installation is straightforward: bolt the included mounting brackets to the trailer frame and insert the jacks. Operation is manual and tool-friendly, so routine setup and teardown at campsites are quick even for first-time users.

• Comes as a complete kit: four jacks, mounting brackets, and two steel pins.
• Foot pad base and drop-leg design enable quick deployment without specialized tools.
• Compact storage dimensions when retracted for convenient transport and stowage.

Who is this for? TENFUN Trailer Stabilizer Jacks are made for RV owners, weekend campers, and small-trailer users who want a simple, effective way to reduce interior movement and improve campsite comfort. If you need reliable corner stabilization without complicated installation or heavy equipment, this four-pack provides practical support for most travel trailers and campers. Not intended as axle jacks for lifting; use them for stabilization and leveling only.
