Verdict first: at the low-profile 3-ton size the Pittsburgh and the Daytona "Professional" publish the same numbers — 3-1/8 in to 19-7/8 in, 6,000 lb working load, 90-day warranty — within a pound of each other. On those two, buy whichever is cheaper on the day, because Harbor Freight is describing the same capability twice. The jack that genuinely separates the brands is the Daytona Superduty: 3-3/4 in to 23-1/8 in of lift and a three-year warranty against ninety days. That warranty is the single biggest difference on this page and it is not a spec anyone puts in a comparison table.
The published figures, side by side
| Pittsburgh 3T | Pittsburgh 3T low-profile | Daytona 3T Professional | Daytona 3T Superduty | |
|---|---|---|---|---|
| Min lift height | 5-1/8 in | 3-1/8 in | 3-1/8 in | 3-3/4 in |
| Max lift height | 18-1/4 in | 19-7/8 in | 19-7/8 in | 23-1/8 in |
| Working load | 6000 lb | 6000 lb | 6000 lb | 6000 lb |
| Product weight | 70 lb | 78 lb | 79 lb | 104 lb |
| Product length | 25 in | 27-1/2 in | 26-7/8 in | 31-1/4 in |
| Handle length | 45 in | 45-5/8 in | Not published | 50-1/4 in |
| Warranty | 90 days | 90 days | 90 days | 3 years |
The pairing that is the same jack
Put the Pittsburgh low-profile and the Daytona Professional next to each other and the published specification is identical on every figure that affects the job: same minimum height, same maximum lift, same working load, same warranty. The only published differences are a pound of product weight and about half an inch of chassis length. If a store has both and one is cheaper, that is the whole decision.
Where the Daytona earns a premium
The Superduty is a different tool, not a trim level. 23-1/8 in of maximum lift is nearly 3-1/4 in more than anything else on this page and puts it in genuine truck and SUV territory; the 31-1/4 in chassis reaches a frame rail from the side of a vehicle; and the warranty runs three years rather than ninety days. The costs are honest ones: 104 lb, and a 50-1/4 in handle that needs floor space to swing.
If reach is what you are after, compare it against the jacks you can order online on the lifted-truck page — the Sunex 66035HR publishes 24.4 in.
Read the warranty as a spec
On a hydraulic tool the warranty is a real signal, because the failure mode people actually see is a ram that starts weeping or a jack that will not hold height. Ninety days barely covers a season of use. Three years is the manufacturer accepting that risk for you, and on this page it is the one difference that separates two otherwise similar house brands.
