Supporting a lifted truck requires jack stands rated for its weight, with 6-ton pair capacity as the recommended minimum for half-ton models.
For the full breakdown, see our best Jack Stands for Lifted Trucks guide.
Heavy duty jack stands for trucks are rated to hold a vehicle steady after lifting. Choosing the right pair starts with your truck’s actual weight, determined by the Gross Vehicle Weight Rating (GVWR) on the driver-side door jamb. A jack lifts a truck; a jack stand holds it there—using them together is the only safe way to work underneath.
How Much Capacity Do Truck Jack Stands Need?
Find the GVWR on the door jamb sticker or owner’s manual, then apply the 3/4 rule: multiply GVWR by 0.75 to estimate the load per support point.
For half-ton trucks such as the F-150, Silverado 1500, or Ram 1500, a 6-ton pair rating is the commonly recommended minimum. For heavier three-quarter-ton or one-ton diesel trucks — F-250, F-350, Silverado 2500HD and 3500HD — 12-ton stands provide a safer margin. Most manufacturers state capacity per pair: a “6-ton pair” delivers 3 tons per stand. When using four stands, each carries roughly a quarter of the load, but always verify the rating format before buying. The pair-versus-per-stand confusion is the most common mistake in selecting truck jack stands.
Your truck’s actual GVWR often exceeds the “half-ton” label by a wide margin. A modern crew-cab half-ton with options can push past 7,000 lb. Checking the door-jamb sticker takes ten seconds and removes all guesswork.
Three Heavy-Duty Jack Stands Worth Considering
The table below compares three models that meet the 6-ton threshold, each with different height ranges and certifications.
| Model | Pair Capacity | Height Range |
|---|---|---|
| BendPak / Ranger RJS-6T | 12,000 lb (5,443 kg) | 15.5 in. – 24.5 in. |
| Martins Industries MJS-6T | 13,200 lb (6.6 tons) | 14 13/16 in. – 22 11/16 in. |
| Canadian Tire Certified 6-Ton | 11,998 lb (5,442 kg) | 15.98 in. – 23.54 in. |
Each uses a ratchet or pin locking system with wide bases for stability. The BendPak offers the tallest maximum height at 24.5 inches; the Martins has the lowest minimum at just under 15 inches—easier to slide under a truck with limited clearance.
What To Check Before You Buy
Three factors determine whether a jack stand works for your truck: height range, capacity margin, and locking mechanism.
The minimum height must fit under the truck at your chosen lift point; the maximum must provide enough clearance for your work. Measure your truck’s clearance at factory lift points—frame rails or axle—rather than guessing from curb height, because suspension droop changes geometry once wheels leave the ground.
Capacity margin is the second checkpoint. Even if a 6-ton pair meets your GVWR estimate, a 12-ton pair adds room for heavier accessories, steel bumpers, or a slide-in camper. The cost difference between a 6-ton and 12-ton set is modest compared to an under-rated failure.
Locking mechanism quality matters because a jack stand’s only job is to stay locked. Ratchet-style stands with positive engagement—where you can see and hear each pin seat—are standard for heavy-duty use. Avoid spring-loaded or friction-only mechanisms for truck-weight applications.
Always place jack stands on a firm, even surface and confirm the locking mechanism engages fully before transferring weight from the jack. A properly matched set—chosen by GVWR, not model name—makes truck maintenance safe and repeatable.
FAQs
Are 6-ton jack stands enough for a diesel truck?
For a three-quarter-ton or one-ton diesel truck, 6-ton pair stands are often insufficient because the diesel engine adds substantial front-axle weight. The safer choice is a 12-ton pair, providing margin for the higher GVWR common on diesel pickups.
Does “6-ton pair” mean each stand holds 6 tons?
No. Most manufacturers rate jack stands by pair capacity, so a “6-ton pair” supports 6 tons total across both stands—roughly 3 tons per stand. When using four stands, each carries about a quarter of the vehicle’s load.
How do I find my truck’s GVWR?
The Gross Vehicle Weight Rating is printed on a sticker inside the driver-side door jamb and listed in the owner’s manual. It represents the maximum loaded weight including passengers, cargo, and accessories. Use this number with the 3/4 rule to estimate the load each jack stand needs to support.
