What TowSifter does
A truck or SUV doesn't have one towing capacity. The figure moves — sometimes by thousands of pounds — with engine, drivetrain, cab and bed configuration, rear axle ratio, and whether a factory tow package is fitted. Two trucks side by side on the same lot can be rated worlds apart.
TowSifter takes a year, make, and configuration and returns the manufacturer-rated maximum towing capacity, payload, gross combined weight rating (GCWR), and the trailer hitch class that setup calls for — plus the specific gear it implies. You can look up your vehicle in a few taps.
OEM-first, by policy
Our sourcing order is deliberate and it never changes:
- Manufacturer documents first. Official OEM towing guides and trailering charts are the gold standard. When one exists for a vehicle, we read the figure straight from it and cite it.
- Manufacturer spec pages next.Where a formal towing guide isn't published, we fall back to the manufacturer's own specification pages before anything else.
- Everything else is flagged.If a clean OEM source can't be found and a figure comes from a secondary source or an estimate, we say so — plainly, on the page, next to the number.
Confidence flags, not false certainty
Every result carries a confidence flag so you always know what you're looking at:
- ✓ High confidence — read from an OEM towing guide or manufacturer spec page.
- ⚠ Verify with OEM — extracted from a source that is pending confirmation against the official guide.
- ~ Estimate only — no OEM guide could be cleanly sourced; treat the figure as a starting point, not gospel.
We would rather show you an honest “verify this” than a confident number we can't stand behind. Spot something off on any page? There's a Notice something wrong?link right next to the confidence flag — tell us and we'll re-check the source.
Always confirm against your door-jamb sticker.The single most authoritative number for your specific vehicle is printed on the sticker inside the driver's-side door jamb, and the towing figures in your owner's manual. No database — ours included — overrides what the manufacturer stamped on your truck. Match your trailer to the lowest relevant limit and verify before you haul.
How we make money
TowSifter is free and always will be. Some of the gear links on the site are affiliate links — if you buy through one, we may earn a small commission at no extra cost to you. That revenue keeps the lookups free; it never changes which figure we report or how confident we claim to be. The specs are the specs.
