The 2020 F-Series Super Duty Tremor Off-Road Package, available for XLT, Lariat, King Ranch and Platinum F-250 and F-350 Super Duty, is powered by an all-new 7.3-liter gas V8 or third-generation 6.7-liter Power Stroke® diesel and can be specified for 4x4 single-rear-wheel SuperCrew trucks with a 6.75-foot box. Unique to Tremor is a new rock-crawl mode, which is optimized to operate in 4x4 low and is enabled by the standard TorqShift® 10-speed automatic transmission. Tremor trucks equipped with the 7.3-liter gas engine have a 53:1 crawl ratio while those equipped with the 6.7- liter diesel engine have a 44:1 crawl ratio. Super Duty gets Trail Control™ which functions in any mode like cruise control for off-road driving. The Tremor Off-Road Package will be available when the 2020 Super Duty launches later this year.
