Ford's new Tremor Package proves ready to play at the off-road playground
Before test driving the 2020 Ford F-350, I climbed to the rim of the Custom Landscape Materials Big Horn Quarry near Wickenburg, Arizona to whet my appetite for what lay ahead. With the excitement of a child arriving at an amusement park and assessing the rides, I eyeballed the off-road playground with its snaking track that started with a climb over a stretch of jagged rocks that led to steep uphill and downhill grades; over patches of deep, gooey mud; through water crossings; and across off-camber sidehills at sharp angles. I was enthralled.
The track was designed by Ford Trucks engineer Bobby Keith to show off the prowess of the 2020 Ford Super Duty when equipped with its new Tremor Off-Road Package. The 1.1-mile-long test track is the most extreme course Keith has ever built.

What is the Ford Super Duty Tremor Off-Road Package?
The Tremor Off-Road Package is a collection of off-road hardware, as well as unique tuning for the truck's steering and a smaller sway bar to provide greater maneuverability in tight turns and over uneven terrain. Elevating the truck are beefy Goodyear tires mounted on a set of unique 18-inch matte-finished black wheels, plus an extra two inches of lift giving the pickup a best-in-class 10.8 inches of ground clearance and the ability to ford nearly three feet of water. Aiding with the best approach and departure angles of any Super Duty ever is a 5-inch shorter air dam that provides impressive 31.65-degree and 24.51-degree angles, respectively.
Also unique to the package is rock-crawl mode; an upgraded suspension with different spring rates; off-road running boards for damage control; and skid plates from the FX4. Tremor uses a locking rear differential that engages with electronic shift-on-the-fly, and a new Dana limited-slip front differential. Trail Control, a crawl program that debuted on the Ford F-150 Raptor and Ranger operates like a cruise control for uphills and rough terrain.
The Tremor package ($3,975) can be ordered can be ordered on XLT, Lariat, King Ranch and Platinum trims for F-250 and F-350 models, powered by the all-new 7.3-liter gas V8 or the updated third-generation diesel engine. It can be specified for 4x4 single-rear-wheel SuperCrew trucks with a 6.75-foot box. Available as a factory-ordered or dealer-installed package is a $3,000 Warn winch add-on with synthetic line (rather than steel cable) that is integrated into the front bumper; it meets crash standards and is operated by a wireless remote.
Of note, towing and payload are similar to non-Tremor models that command best-in-class ratings.

How does it stack up against the competition?
The Super Duty with the Tremor Off-Road Package takes Ford's FX4 models to a new level. Rock-crawl mode and Trail Control get traction to the ground and provide plenty of grunt (models equipped with a 7.3-liter gas engine have a 53:1 crawl ratio while trucks with the 6.7-liter diesel power plant have a 44:1 crawl ratio).
It gets high marks for its serious off-road cred and goes beyond similar offerings from Ram and GM. Ram's Power Wagon is available on 2500 models only. While the Power Wagon has many appealing attributes, such as a disconnecting sway bar and locking differentials for both the front and rear, Tremor's set-up works laudably. The Super Duty Tremor's smaller 24 mm sway bar and other engineering upgrades were effective for twist and articulation and gave a smooth, mannered ride with progressive-rate springs for duty on rugged terrain, as well as for heavy-duty towing performance.
General Motors' AT4 grade is available on Chevrolet Silverado 2500 and 2500, and GMC Sierra 2500 and 3500. It adds some similar attributes but the Tremor pulls ahead with greater towing capacity, payload capacity, ground clearance, and water-fording depth than the Ram and GM trucks.
The GMC, Ram, and Ford trucks have the best-appointed interiors of the lot. All have new camera technologies, with GM's 15-camera view being the best pick for towing tasks.

How did it do?
There's no doubting that the Tremor Off-Road Package is capable of doing exactly what it was designed for. In combination with the prowess of the F-350, as tested the Super Duty took on 33-inches of water fording with ease, smoothly held its own on a 15-degree off-camber hill, walked over 45-degree angled logs, and scooted up a 29-degree hill climb without hesitation. The Ford's camera system helped with low-sitting obstacles and peeking over hills, as advertised.
Ford Trucks engineers have made the package able to conquer some of the toughest terrain you're likely to find when you're on the farm, up a back road, or simply off the beaten path. The model isn't a Jeep competitor and it's not meant to be. This heavy-duty truck is able to get work and play done, son.
