Perché questo prodotto

Perché il Ultra-Fab Stacker Jacks 2-Pack?

Ultra-Fab stack jacks are the direct competitor to Camco's version. Same 6,000 lb rating, same 17-inch range, same bumper storage concept. At 24 lbs for two, they are heavier than Camco's 3.9 lb pair — that extra weight comes from thicker steel tubing. If you want a beefier stack jack that feels more solid, these deliver.

“They do the job: These are stronger than they look. they look pretty flimsy when I got them but they seem to work well. I have seen the same stands in local stores for more than twice the price. I am not using them on anything heavy duty I admit.”

Domande frequenti

There is nothing to fit — these stand on the ground under the frame and adjust from 11 to 17 inches. Measure the gap between your frame rail and the ground at the spot you plan to use. If it falls outside that range, these are the wrong height class, not the wrong product.

6,000 lbs per jack — not per set. This is a set of 2, so the figure on the box may appear as a total; it is 6,000 lbs times 2, and no single jack does more than its own share. Match the per-jack number against the weight actually resting on that corner, which is a fraction of the trailer's weight, not all of it.

No — the manufacturer says so directly: "For stabilizing only — do not use for lifting." A stabilizer stops the trailer rocking when you walk around inside it. It is not a lift, and it is not a jack stand. Raising a trailer on stabilizers can bend the frame at the mounting point, and it puts the whole thing on hardware that was never rated to hold it up. Use a bottle jack at a designated lift point, then support the load on stands, and only then go underneath.

This is a set of 2. Four is the normal number for a travel trailer — one at each corner — so a pair covers one end and most owners end up buying two sets. Placing them just inside the corners rather than at the extreme ends does more to stop the rocking, because that is where the frame is stiffest.

Put something under the foot. A jack pad or a scrap of dimensional lumber spreads the load so the foot does not press into gravel, sand or soft turf. This is not about grip — a stabilizer is not trying to resist sliding, it is trying not to sink. On asphalt in summer heat, a pad also keeps the foot from leaving a dent you will be asked about.
