The Tremor Off-Road Package is truly capable, as one would expect from Super Duty, with towing and payload ratings similar to non-Tremor models. Both workhorse and adventure machine, the package is available for XLT, Lariat, King Ranch and Platinum F-250 and F-350 Super Duty with all-new 7.3-liter gas V8 or third-generation 6.7-liter Power Stroke® diesel. Tremor can be specified for 4x4 single-rear-wheel SuperCrew trucks with a 6.75-foot box; F-250 models also require the high-capacity trailer tow package

Off-road upgrades start with a set of aggressive 35-inch-diameter Goodyear Wrangler Duratrac maximum-traction tires - the largest diameter tires available on a heavy-duty pickup - mounted on a set of unique 18-inch matte-finished black wheels. These tires, combined with a 2-inch front-end lift and shorter air dam, result in an impressive 10.8 inches of ground clearance, best-in-class water fording of 33 inches, and the best approach and departure angles of any Super Duty ever - 31.65 degrees and 24.51 degrees, respectively.
