Pro Comp’s wicked new 4-link suspension kits provide up to 4-6 inches of lift while providing optimum control and stability for the 2017-19 Ford Super Duty. These new kits maintain the ideal roll center while increasing wheel travel for improved off-road performance. Specially-engineered brackets position the extended-length control arms in the perfect 4-link geometry to deliver compliant ride quality and minimal caster and pinion angle change. Heavy duty, tubular upper control arms can be adjusted on-vehicle for easy caster adjustments. An added crossmember between the 4-link brackets provides rock protection for your transfer case and custom-stamped steel lower arms are engineered to clear 37-inch tires at full steer.
