- ford is adding an off-road tremor package to the super duty range of heavy-duty trucks.
- available on crew-cab models with either of the available upgrade engines, the tremor package adds off-road equipment such as meaty tires, a lifted suspension, and other rugged bits.
- the tremor package will be available by the end of 2019 on the updated 2020 f-250 and f-350 models.
the ram 2500 has the power wagon, the gmc sierra hd has the at4, and now ford's super duty pickup has its own in-house off-road trim. called the tremor, this new option package will be rolling out onto the updated 2020 ford super duty range, and it offers significant off-road equipment compared to the mostly appearance-based fx4 package ford currently offers.
key mechanical changes for the tremor include a lift kit that raises the front suspension by two inches, a front axle with a limited-slip differential, and a locking rear differential. a set of 35-inch goodyear wrangler duratrac off-road tires wrap around 18-inch matte black wheels. the tremor also has different shocks than those on a standard super duty. the front air dam is five inches higher than normal, which helps the truck's approach angle, and ford says that the tremor model can ford water up to 33 inches deep. a new rock-crawl mode operates in low range, and ford also has a trail control system that operates like a sort of off-road cruise control.
the name tremor may sound familiar. that's because it was previously used on a street-focused version of the f-150 a few years ago. the name has now been repurposed for this off-road version of the super duty, although the sticker slapped onto the tailgate looks pretty similar to us.
while there's no pricing information out yet, the tremor package will be available on xlt, lariat, king ranch, and platinum trim levels. it comes only with the crew-cab body style and either of the f-250 and f-350's upgrade engines: the new 7.3-liter gasoline v-8 and the 6.7-liter turbo-diesel. we estimate the package will cost somewhere around $2000 when it goes on sale at the end of 2019.
