Sturdy Built Replacement Drop Foot for Trailer Jacks 1 3/4" Square — Zinc-Coated, 2,500 lb Capacity

Sturdy Built's 1 3/4" square replacement drop foot restores a corroded or damaged trailer jack foot to full function and fits most 2,500 lb capacity square drop-foot jacks.

Over time the exposed lower section of a trailer jack—the drop foot—can rust, bend, or wear away. This zinc-coated replacement part is sized for standard 1 3/4" square jack legs rated for up to 2,500 pounds, letting you refresh the working end of your jack without replacing the entire assembly. The finish matches many common zinc-plated jacks and offers improved resistance to corrosion so the foot stays serviceable season after season.

Will this replacement part fit my trailer jack?

Measure your jack leg: this drop foot is designed for a 1 3/4" square inner section and is compatible with most square drop-foot jacks rated at 2,500 lb. Check for the cotter-pin hole spacing and confirm your jack accepts a removable drop foot before ordering.

• Inner dimension: 1 3/4" square to slide onto the jack leg
• Capacity match: suits jacks rated around 2,500 lb
• Mounting: accommodates a cotter pin (cotter pin not included)
• Finish: zinc coating for visual and corrosion match

How durable and weather-resistant is the zinc coating?

The zinc plating slows surface corrosion compared with bare steel and helps the replacement foot maintain appearance and function in outdoor use. It’s intended to match the look and basic protection level of common zinc-plated trailer jacks, though long-term resistance depends on exposure and maintenance.

• Zinc coating for basic corrosion resistance and improved lifespan
• Suitable for typical road and storage conditions when cleaned and inspected
• Not a stainless steel part—consider additional rust prevention in harsh environments

How do I install the drop foot and what tools are needed?

Installation is straightforward: slide the replacement foot over the jack leg, align the cotter-pin hole to your jack’s pin position, then secure with a cotter pin. No special tools are required—just remove the damaged foot, slide the new piece on, and insert a new cotter pin.

• Remove old foot from jack leg (may need penetrating oil if corroded)
• Slide replacement onto 1 3/4" square leg and align holes
• Secure with appropriate cotter pin (not included)
• Quick visual check for fit and alignment before use

What should I inspect after replacement and during routine checks?

After installing the new drop foot, ensure the leg slides freely and the cotter pin is snug and properly bent. Periodically inspect for corrosion, deformation, and secure fasteners—replace cotter pins when worn and reapply protective coatings if surface rust appears.

• Verify cotter pin hole alignment and secure pin placement
• Check for movement or looseness between foot and jack leg
• Look for chips in the zinc coating and touch up or protect if needed
• Inspect load-bearing surfaces for wear before each towing trip
