Four-corner stack jacks in heavy steel — 6,000 lbs per jack, 17-inch range
Last reviewed: March 2026
Four-pack of steel stack jacks for complete four-corner stabilization. Each jack handles 6,000 lbs with 17 inches of height adjustment. At 48 lbs total for four, these are heavier than Camco stack jacks but built with thicker steel tubing.
At a glance
Why this product
Four jacks for all four corners at 6,000 lbs each. The Ultra-Fab version uses heavier steel than Camco, which you can feel in the 48 lb total weight. That heft translates to less flex under load. The trade-off is obvious — they weigh six times what the Camco 4-pack weighs. If stability matters more than weight, these are the pick.
