Stabilizer Jacks

Match the jack’s weight capacity to the tongue or supported load of your vehicle/trailer, choose a mounting style that fits your frame or bumper, and check lift range to ensure it reaches the ground and desired height; also consider materials (steel vs. stainless) for corrosion resistance

Select a jack with a rated capacity equal to or greater than the static load it will support; capacities are usually listed per jack (e.g., 2,000 lb each), and for paired installations double the single-jack rating to estimate total support

Manual jacks use a crank or screw mechanism and are typically lower cost and simpler to repair, while electric jacks use a motor for faster, hands-free operation and may require a 12V power source and periodic electrical maintenance

Look for powder-coated or galvanised steel and stainless-steel fasteners for better corrosion resistance; sealed or painted surfaces and protective boots on moving parts help reduce wear from road grime and moisture

Install following the manufacturer’s torque and bracket-placement instructions, secure all hardware, periodically lubricate moving parts, inspect for rust or bent components, and test operation under load before regular use

Stabilizer jacks work best on firm, level surfaces; use jack pads, blocks, or ground anchors to distribute load on soft or uneven ground and avoid placing jacks on loose or sinking surfaces without proper support

Ensure your vehicle or trailer 12V system can supply the jack’s starting current, use proper gauge wiring and fuses per the jack’s specifications, and protect connectors from moisture and corrosion to prevent electrical failure
