Features to know about

Handles Heavy Loads with Ease: 25,000-lb 2-Speed Lift Power

When you need real muscle to handle industrial or construction trailers, this square 2-speed jack gets the job done. It’s rated for a full 25,000 lbs and gives you two gearing options—1" of lift every 4-1/2 turns in high gear or 1" every 34-1/2 turns in low gear. That means you can switch between fast travel when the load is light and slow, steady turns when it’s heavy. The built-in grease zerks keep the mechanism running smooth for long life.

Quick Adjustments on the Job: Drop Leg with Spring Return

The drop leg has an 11-1/2" travel range and a spring return that retracts automatically with a tap of your foot. No need to wrestle with pins or clips—the side-positioned plunger lines up easily and keeps your hands clear of pinch points. When time matters at setup or breakdown, this feature saves extra steps and keeps things moving quickly.

Stable on Any Ground: Wide Footplate and Heavy-Duty Tubes

A 9-7/8" round footplate spreads the load so the jack won’t sink into soft ground. The strong steel tubing—4-3/8" outer width and 4" inner width—gives a solid, steady feel even under full capacity. Whether you’re loading or leveling, you get the kind of stability that keeps everything planted and predictable.

Built to Last: Simple Maintenance and Tough Finish

This jack’s industrial-sized tubing and black painted finish stand up to demanding use in farmyards, yards, or work sites. The weld-on mount is solid, the sidewind handle turns easily, and grease fittings make upkeep simple. Retracted height is 30" and extended height is 43", giving you 13" of lift plus adjustable drop leg travel for maximum range when conditions vary.

This jack was a good price. After shopping around I found etrailer has the same item for 50% less than anyone else. The shipment was on time and the heavy metal jack did some damage to the shipping box but that is understandable (the jack was in perfect condition). We were also pleased the crank handle came with it at no extra charge as it was an extra $50+ everywhere else.
by:
Jack arrived in good shape despite ups damaging the packaging so badly that it was returned once and the second one having nothing but the shipping label taped to the jack.
