Why this product

Why the 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.

Frequently Asked Questions

The Ultra-Fab Stacker Jacks 2-Pack supports up to 6,000 lbs per jack. Compatible with most travel trailers and fifth wheels. Mounts to your frame's existing jack brackets. Use our compatibility checker below to verify your RV type.

The Ultra-Fab Stacker Jacks 2-Pack handles 6000.0 lbs. That covers most Class A motorhomes, fifth wheels, and travel trailers. Don't stack beyond the rated limit—overloading cracks the material and voids your warranty. Know your axle weight, not just GVWR.

Setup takes under 5 minutes. Position the Ultra-Fab Stacker Jacks 2-Pack where needed, adjust to the right height, and you're level. No special tools required—completely tool-free. Straightforward enough that you'll have it down after one use.

Yes. The Ultra-Fab Stacker Jacks 2-Pack has a textured anti-slip surface that grips on gravel, dirt, grass, and sand. On very soft ground, place a wide board underneath to spread the load. Avoid mud—nothing grips well in mud. The surface also handles wet concrete and asphalt without slipping.

The Ultra-Fab Stacker Jacks 2-Pack is made from steel. UV-resistant—won't crack in sun. Freeze-proof down to -40°F. Most owners get 5+ years of regular use. Replace if you see cracks or deformation.

No storage bag included with the Ultra-Fab Stacker Jacks 2-Pack. Most owners use a heavy-duty tote or mesh bag from a hardware store—$5–$10 solves the problem. Keep the pieces together in your RV's basement compartment to avoid losing blocks at the campsite.
