Ford refers to its heavy duty trailer kit for the F-250 Super Duty pickup truck as the High Capacity Trailer Tow Package, or the 535 option. It?s an improvement over the standard tow package that the F-250, the F-350 and the F-450 Super Duty pickup trucks already come with.
Adding the Ford High Capacity Trailer Tow Package on your F-250 upgrades a lot of its components, in addition to equipping it with some new features. The standard tow package comes with 7 wire harness with 4 and 7 pin connectors, hitch receiver, smart trailer tow connector, trailer brake wiring, Tow/Haul modes, trailer brake controller and trailer sway control.
The High Capacity Trailer upgrades adds lightweight Aluminum wheels with what Ford calls a ?Polished Platinum? finish to the whole setup, as well as a rear axle upgrade and increased GCW. An F-250 without a trailer tow package comes with a standard 2 ? inch receiver, while an upgraded truck uses a larger 3 inch receiver. You also get a 2 ? inch reducer adapter for it, so you can still use your existing mounts without having to upgrade.
