It seems like each model year yields new variations of pickup trucks, so it comes as little surprise Ford is adding a new trim level to the 2020 F-Series Super Duty. The name of this trim is actually familiar, it’s called the Tremor.
For those who remember the F-150 Tremor from earlier this decade; this one is nothing like that one. The F-150 Tremor was a single cab, EcoBoost-powered street performance truck. The 2020 Super Duty Tremor is geared for off-road performance, despite the Tremor badge on the sides.
Ford has focused on function with the Tremor, giving it unique Tremor-badged shocks that have more oil capacity than the stock units on the Super Duty. Subsequently, the progressive rate springs have been tuned to favor off-roading over heavy towing. Ford says the Super Duty’s rear stabilizer has also been modified to handle greater articulation.
As you’ve probably picked up by now, the changes to the Super Duty’s suspension have had a negative impact on its payload and towing figures, though Ford has not disclosed the exact impact at this time.
Resting at all four corners are 35-inch Goodyear Wrangler Duratrac tires over unique 18-inch wheels. The big off-road tires are made possible by a 30 mm lift in the front and 40 mm lift in the back. Combined, the modifications give the Super Duty Tremor 10.8 inches of ground clearance and 33 inches of fording power. Ford says the front axle is also unique to the Super Duty to allow for better approach and departure angles, while a Dana limited slip differential will help get the power to those beefy tires.
Along with the new differential, Ford has also added a rock-crawl mode that can be activated with the 4×4 system is in low.
There’s some constraints to getting the Tremor package added to a 2020 Super Duty. Ford says buyers must opt for the crew cab model and select between Ford’s new 7.3-liter V-8 or Powerstroke 6.7-liter diesel V-8; the package cannot be added to the base 6.2-liter V-8.
So far Ford isn’t saying how much the Tremor package is going to cost. The price tag of this “pre-modified” pickup will be revealed closer to its launch later this year.
