The Blackhawk B6350 is a 3.5-ton hydraulic floor jack built for trucks, full-size SUVs, and serious home garage use. It lifts from 5.125 inches to 22 inches, uses a dual-piston fast-lift pump, and is consistently reported to hold position without noticeable hydraulic drop under extended load — something budget jacks regularly fail at. It is heavy, it is not cheap, and it will not fit under a sports car. If you own an F-150, a Silverado, or anything that sits high and weighs heavy — it is the right tool.

Hank’s Verdict
The B6350 does what most floor jacks quietly fail at — it holds position under a heavy truck without drifting. The dual-piston pump gets you to working height in four or five strokes. The 22-inch max lift clears rear axles on full-size pickups where cheaper jacks run out of travel. One honest gripe: the release valve is more sensitive than ideal — a half-turn too far and the truck drops faster than you want. Takes a few uses to find the right feel. Heavy too — dragging it solo across a large garage floor is a genuine workout. Set those aside and there is not a more reliable steel floor jack for trucks at this price.
See It Before You Buy It
What Arrives in the Box
The B6350 ships as a single assembled unit. No loose hardware to hunt down on arrival.
Before first use: inspect the hydraulic cylinder for shipping damage, confirm the release valve moves freely, and cycle the jack up and down three times with no load to clear any air in the cylinder.
First impression out of the box is weight — heavier than most consumer floor jacks, which is a good sign. Wheels roll clean on flat concrete and the handle grip is solid rubber.
Watch the release valve on unboxing. Give it three open-and-close cycles before putting load on the jack. Some units ship with threads slightly stiff — better to work that out before you are under a truck.
Why the B6350 Earns Its Price
Most home mechanics buy a floor jack once, regret it twice, and then buy the right one. The first jack is usually a budget unit that lifts fine on day one and starts drifting by month three. You set it under an axle, walk away to grab a wrench, and come back to find the truck has settled two inches. That is not bad luck. That is a hydraulic seal problem — and it is the thing the B6350 is engineered to avoid.
The hydraulic cylinder is oversized compared to consumer-grade alternatives. The seals are rated for sustained load. The steel construction does not flex the way cast aluminium jacks can when a heavy truck is sitting on them. For a full-size pickup or a heavy SUV, that rigidity matters.
If you drive a sports car, a lowered sedan, or anything that sits under six inches at the sill, the 5.125-inch minimum height will not clear. See the low profile floor jack options instead. And whatever jack you use, always pair it with rated jack stands before going under any vehicle — a floor jack is a lifting tool, not a support tool.
Performance Scorecard
Rated across five categories that matter for a heavy-duty home garage floor jack.
Specs at a Glance
The Numbers That Matter
5.125 in minimum height — clears the frame on stock-height trucks and full-size SUVs. Rules out sports cars and lowered vehicles completely.
22 in maximum height — clears the rear axle on an F-150 or Silverado without a saddle extension. Extensions introduce wobble that solid contact avoids.
3.5 ton (7,700 lbs) — rated for one-corner lifting on heavy-duty pickups. More than sufficient for any passenger truck.
Dual-piston pump — roughly half the strokes of a single-piston jack to reach working height.
~68 lbs — heavier than aluminium alternatives. The tradeoff is structural rigidity under sustained load.
The Dual-Piston Pump: Why It Matters
Standard floor jacks use a single piston. Each stroke moves a fixed volume of hydraulic fluid. On a heavy truck that means ten to fifteen strokes to reach working height. The B6350 uses two pistons working together, moving roughly twice the fluid per stroke. Four to five strokes and the truck is off the ground.
The pump also engages from the first stroke without a dead zone at the start of the handle travel — a common complaint on cheaper single-piston jacks where the first two or three strokes feel like nothing is happening.
For a deeper look at hydraulic systems and what to do when a floor jack starts losing pressure, the Workbench maintenance guide covers bleeding, fluid replacement, and seal troubleshooting across all jack types.
Safety Rules for Heavy-Duty Floor Jacks
Four Rules. No Exceptions.
Pros and Cons
What Works
- Consistently reported to hold without noticeable hydraulic drop under sustained load
- Dual-piston pump — 4 to 5 strokes to working height on a full-size truck
- 22-inch max lift clears rear axles on pickups and full-size SUVs
- Steel construction — more rigid than aluminium jacks under heavy vehicles
- Saddle reaches factory jack points on F-150 and Silverado without extension
- Wide wheelbase — stable on flat concrete with heavy loads
What to Watch
- Heavy (~68 lbs) — solo movement across a large garage is real effort
- 5.125-inch min height rules out all sports cars and lowered vehicles
- Release valve is sensitive — takes several uses to find the right feel
- Takes up more storage space than compact alternatives
- Price reflects the build — not a budget option

The B6350 is a specific tool for a specific vehicle type. Here is how it stacks up so you can match the right jack to what you drive.
| Jack | Capacity | Min Height | Max Height | Pump | Best For |
|---|---|---|---|---|---|
| Blackhawk B6350 | 3.5 ton | 5.125 in | 22 in | Dual piston | Trucks. Holds under sustained load. |
| ARCAN A20019 3T | 3 ton | 3.25 in | 19.5 in | Single piston | Sports cars. Lighter body. |
| VEVOR 3T Low Profile | 3 ton | 2.8 in | 19.7 in | Single piston | Budget, low-clearance vehicles. |
| Torin Blackjack 3T | 3 ton | 5.25 in | 18.1 in | Single piston | All-rounder. Shorter max height. |
For low-clearance vehicles, the ARCAN A20019 is the right call. For trucks needing 20+ inches of lift, the B6350 has no real competition at this price. Full breakdown in the Best Hydraulic Jacks guide. Also see the car lift section and Hank’s maintenance guides.
Hydraulic Hold: What Users Report
The most common floor jack failure mode is slow hydraulic bleed-down under sustained load. The jack lifts fine but left under a vehicle for 20 to 30 minutes, it quietly settles. Based on manufacturer specifications and aggregated user feedback across hundreds of verified reviews, the B6350 consistently stands out in this area compared to similarly priced alternatives.
Reports consistently show minimal to no noticeable drop over extended use on the B6350 — especially compared to budget jacks which frequently show visible settling within 20 to 30 minutes under heavy vehicles. That reliability under sustained load is the core reason mechanics who work on trucks buy this jack over cheaper alternatives, and keep it.
Best Alternative
If the 5.125-inch minimum height does not fit your vehicle, the ARCAN A20019 3-ton low profile jack is the next recommendation. It drops to 3.25 inches, handles sedans and sports cars the B6350 cannot reach, and weighs less if portability matters.
For a mixed fleet — truck, daily driver, weekend project car — the honest answer is one jack matched to each job. If you can only own one, buy for your heaviest vehicle.
For anyone lifting vehicles regularly, the car lift buying guide covers the next step up. The Workbench has everything on hydraulic fluid types and jack maintenance.
Should You Buy It?
If you own a full-size truck, a heavy SUV, or any vehicle that needs more than 18 inches of lift height — yes. The B6350 is built for that job and nothing in its class holds pressure as reliably at this price point.
If you drive a sports car, a compact, or anything that sits low — this is the wrong jack. Head to the Best Hydraulic Jacks guide and filter by minimum height instead.
Buy it for trucks. Use it for trucks. It will not let you down.
