Ford changed the 5.2-liter engine and its blower for the Raptor. Engineers swapped the pulley and reworked the programming to maximize low-end torque for off-road use. Additionally, the exhaust manifolds are now cast stainless steel, the oil pan is deeper to help prevent starvation on steep grades, and the new air intake inlet allows for 66 percent increased volume. Versus an EcoBoost-powered Raptor, the R has a different, beefier front axle, a revised torque converter, and a whole slew of Code Orange accents and “R” badging. While 35-inch tires are the default option on the base truck, the R gets 37s across the board. Ground clearance is a massive 13.1 inches, and wheel travel is 13 inches up front and 14.1 inches at the back.
