Ford Super Duty Tremor vs FX4 – What Makes the Tremor so Off-Road Ready?

Ford is stepping up its heavy duty off-road game with the new Tremor package, but exactly how much further does it take things than the FX4?

The FX4 off-road package has been around for some time at Ford trucks and can be had on both the half-ton pickups and the HDs. On the big trucks, it brings along four upgrades, those being Rancho front and rear shocks, Transfer case and fuel tank skid plates, hill descent control, and an FX4 off-road box decal.

An electronic-locking rear differential is also available on these FX4 trucks, though it’s not technically built into the package. A number of different tire choices can be had with the FX4 as well, but the most aggressive still doesn’t come close to the Tremor.

Looking to take on the venerable Ram Power Wagon, the Tremor arrives packing everything in the FX4 package plus a two-inch front end lift, 35-inch Goodyear Wrangler Duratrac tires, a Dana limited-slip differential in the front end, specially tuned springs, 1.7-inch piston twin-tube dampers, longer axle vent tubes, a tiny front plastic air dam, a new rock crawl mode, and running boards taken from the Raptor that do not hang down low beneath the truck and also provide some protection to the rockers.

The resulting numbers for the Tremor fall here: 10.8 inches of ground clearance, water fording of 33 inches, 31.65 degrees of approach and 24.51 degrees of departure.

Perspective buyers will be able to get a Tremor in only a single body style, that being a single rear-wheel SuperCrew with a 6.75-foot box, though four different trims will be available: XLT, Lariat, King Ranch and Platinum.

Both the new 7.3-liter naturally aspirated gas V8 and 6.7-liter turbodiesel will be available under the hood of this off-road truck. While we still don’t have numbers on the diesel, we now know that the gas engine make 430 horsepower and 475 lb-ft of torque.
