Buying Guide
Key considerations for selecting stabilizer jacks include load capacity, height range, ease of mounting, and corrosion resistance. For cargo trailers, aim for 1000 lbs static capacity per jack to handle typical trailer weights with some margin. Look for telescoping or folding designs that extend to at least 18 inches for better clearance on uneven ground. A zinc coating or electrophoretic finish improves rust resistance in outdoor environments. Consider whether you want a two-pack or four-pack based on trailer size and axle count. Ensure mounting hardware compatibility with your trailer frame and rail spacing.
