Ford’s new, 14th-generation F-150 will reach showrooms in fall 2020 as a 2021 model, and information about the trim level hierarchy is beginning to emerge. An ordering guide sent to Autoblog by a dealer who asked to remain anonymous confirms the off-road-oriented FX4 package will return, unsurprisingly, and it will offer adventurers a new feature in exchange for a slightly higher price.
FX4-equipped trucks will receive an additional driving mode named Rock-Crawl, according to the documents we received. It’s a hand-me-down from the Super Duty Tremor introduced for the 2020 model year. In the Tremor, Rock-Crawl operates in 4×4 Low and modifies the transmission and traction control settings, among other parameters. It notably detects when one of the front wheels loses traction and uses the truck’s brakes to send power to the wheel that still has grip. We expect the F-150 will receive similar technology.
We can reveal the FX4 package will also include off-road-tuned front shocks, skid plates to protect the front differential, the transfer case and the fuel tank, hill descent control and tray-style floor liners users can remove and hose off. All-terrain tires (either BSW or OWL, depending on the powertrain selected) will be offered at an extra cost. Rock-Crawl aside, the 2021’s FX4 package will be nearly identical to the bundled offered on the 2020 model.
Speaking of powertrains, the FX4 goodies will be available with the 5.0-liter V8, the 3.5-liter EcoBoost V6, the 3.0-liter turbodiesel V6, and the 2.7-liter EcoBoost V6. Four-wheel drive is mandatory, of course; the package was designed to increase the F-150’s off-road capacity. All FX4-equipped trucks will come with an electronic locking rear axle, but its ratio depends on what’s in the engine bay. 5.0-, 3.5- and 3.0-liter trucks get a 3.31:1 axle, while those with the 2.7 receive a 3.55:1 axle. The list of extra-cost options also includes a 3.55:1 axle for the 5.0, the 3.5, and the 3.0 engines and a 3.73:1 for either the 5.0 or the 2.7. Notably, 3.3-powered trucks will not be eligible to receive the FX4 package.
Buyers will be able to add the FX4 package when they select the XL, XLT, Lariat, King Ranch and Platinum trims. It will cost $1,005, according to TFL Truck, which represents a $100 increase over the package offered on the outgoing 13th-generation model. And, while it doesn’t sound like Ford is planning to give its bestselling truck the Tremor treatment, a recent report suggests the smaller Ranger will join the family for the 2022 model year. It’s not too far-fetched to speculate it will receive a Rock-Crawl mode (or something a lot like it) as well.
