Built for diesel Super Duty owners who want 6 inches of lift with factory-correct geometry, this Rough Country M1 lift kit combines coil-spring articulation with radius arm drop brackets that preserve OE caster angles. You'll gain serious ground clearance, level the front-to-rear stance, and accommodate 35"–37" tires without sacrificing driveline health or steering feel.
