2025 Ford Super Duty Tremor Off-Road Package: The Ultimate Heavy-Duty Adventure Truck

What Is the Tremor Off-Road Package?

The Tremor Off-Road Package is Ford’s boldest leap into serious terrain-tackling territory for the F-250 and F-350 Super Duty trucks. While the FX4 package offered respectable off-road prowess, the Tremor takes it several notches higher, integrating serious mechanical upgrades, aggressive styling, and all-terrain readiness without compromising towing and hauling capabilities.

Off-Road Foundation: Tires, Wheels, and Suspension

The Tremor package rides on massive 35-inch Goodyear Wrangler DuraTrac tires wrapped around exclusive 18-inch matte black wheels. These are paired with a factory-installed lift: two inches up front and 1.5 inches at the rear, providing 10.8 inches of ground clearance and 33 inches of water fording depth—essentially up to the lower edge of the headlights.

Advanced Suspension Design

Ford has engineered progressive-rate springs and unique 1.7-inch piston twin-tube dampers, designed in-house to provide a smoother ride at slow speeds and tighter control during high-impact jolts. This makes the Super Duty Tremor equally at home rock-crawling or towing a heavy load through rough backcountry roads.

Engine Choices and Drivetrain Performance

The Tremor Off-Road Package is available with two powerhouse engine options:

• All-new 7.3-liter V8 gasoline engine
• 6.7-liter Power Stroke V8 turbo diesel

These engines offer impressive crawl ratios — 53:1 with the gas engine and 44:1 with the diesel — making steep hill ascents and rock trails more manageable than ever before in a Super Duty truck.

Off-Road Driving Modes and Control Features

Ford has equipped the Tremor package with selectable drive modes including Rock Crawl, Deep Snow/Sand, Slippery, Tow/Haul, Normal, and Eco. The addition of Trail Control — essentially low-speed cruise control for off-roading — allows for precision navigation on complex trails with minimal driver input.

Exterior Enhancements and Off-Road Geometry

A shortened front air dam enhances approach angles, now rated at 31.65 degrees, with a departure angle of 24.51 degrees. While the breakover angle hasn’t been specified, it's a significant improvement over FX4 due to the lifted stance.

Skid plates carry over from the FX4 package, while running boards have been redesigned to sit tighter against the body, offering both sill protection and reduced snag risk on rugged trails. Dana’s limited-slip differential at the front complements the electronic locking rear differential for enhanced traction.

Interior: Function Over Frills

The interior remains consistent with standard Super Duty trims, maintaining the utilitarian focus. There are no unique seats or cabin accents exclusive to the Tremor, aside from a rear-quarter exterior badge. This underscores the Tremor’s mission: performance over appearance.

Trim Levels and Customization

The Tremor package is compatible with most Super Duty trims from XLT up to Platinum. You can also combine it with the Sport Appearance Package to include darkened grilles and aesthetic enhancements. However, the base 6.2-liter V8 is not an option — ensuring only the most capable powerplants are paired with this off-road kit.

How It Compares: Tremor vs Ram Power Wagon

Ford's Tremor competes directly with the Ram Power Wagon. While the Power Wagon boasts front and rear lockers, an electronic sway-bar disconnect, and a factory winch, the Tremor counters with a diesel engine option and higher towing and payload capacities — something no other heavy-duty off-roader currently offers.

Use Case: Off-Roading Meets Workhorse Utility

The Tremor is built for those who need more than just an adventure truck. Whether you're towing a camper into the wilderness or hauling tools up a rocky slope, the Tremor blends serious off-road hardware with Ford’s proven Super Duty toughness.

Expected Pricing and Value

While Ford hasn't released official pricing details, it’s expected to sit above the FX4 package, reflecting its expanded capabilities. It will remain more affordable than a Raptor, yet deliver unmatched utility for off-road enthusiasts who need towing and heavy-duty performance.
