The US Jack is the strongest set here and the pick for best overall. It reached past
47,500 lb on the press when no other stand cleared 40,000, it has the least
side-to-side play in the group at under a tenth of an inch, it offers the
most lift at just over 25.5 inches, and its handle would not release the load
no matter how hard it was pulled. The trade-offs are the $280 price and the
base, which is shorter than several rivals and left it last in the
lift-onto-two-legs test at 297.8 lb.
For most shops the Husky is the better buy. It finished a close second
overall at an average of 3.3, took the top spot in the full-height tipping
test at 199.5 lb thanks to its anti-sink feet, tied for the lead across the
base at 372 lb, and held near 36,000 lb on the press — all for around $90.
The $70 Big Red is the budget alternative, second at full height with 189.5
lb and 36,000 lb on the press, though the test set arrived with a stiff
ratchet bar and a broken lock-pin chain. If a handle knock is the worry, the
Daytona and Sunex had the strongest roll pins at 360 and 340 lb.
Two cautions are worth carrying away. First, the handle test: with only 800
lb on the stand, none of the ratcheting designs kept their load when the
handle was lifted, and the Arcan gave way at 27 lb of upward force. The
locking pins that come with these stands are not decoration — use them.
Second, the ZSP shows what an adjustable-leg stand can do. Both of its stands
broke apart at 95 lb of sideways force, it reached only about 15,000 lb on
the press with its center bar taking the load, and a leg snapped off at
around 5,000 lb when the legs carried it — below the 6,000 lb the pair is
sold to hold. Adjustable-leg stands of this type should stay out of the shop
altogether, and no jack stand of any brand is a substitute for wheel chocks
and a level, hard surface.
