DESCRIPTION:
The Kryptonite 4.5” Super Duty Lift Kit gives your truck the stance, clearance, and capability it deserves. Engineered as a complete system, this kit maintains proper suspension geometry so you keep the ride quality and handling your Super Duty was built for. With 4.5” of front lift and 2” of rear lift, you’ll unlock room for larger, more aggressive tires, and yield a level stance. Strength, precision, and performance come standard.
Engineered for strength, clearance, and control, the Kryptonite Death Grip Radius Arms are built from carbon steel with internal gussets, CNC precision welding, and a durable powder-coated finish for unmatched durability. The hexagonal caster eccentrics let you fine-tune alignment at 0°, 2°, or 4°, while CAD-designed geometry ensures tire clearance and proper suspension performance.
The Kryptonite Track Bar is engineered from heavy-duty steel and features a massive center turnbuckle adjuster, allowing precise on-truck adjustment for this lift. High-strength rod ends and bushings provide improved steering response and eliminate unwanted axle shift, keeping the front end tight under load.
Kryptonite 4.5″ Dual-Rate Lift Coil Springs are forged for real-world performance across harsh terrain, heavy hauls, and daily driving. These precision-engineered, dual-rate springs deliver a smooth ride with rugged load-handling and minimal sag. Shot-peened and finished in black powder-coat for long-term durability, they install directly with no tweaks needed, giving your 4x4 a true 4.5″ front lift.
To match the added height, this kit is paired with Fox 2.0 Performance Series IFP Shocks, tuned specifically for Super Duty trucks running 4–5″ of lift. These monotube shocks use Fox’s race-proven internal floating piston design for consistent damping, smoother on-road comfort, and confident off-road control. Built with a lightweight 6061-T6 aluminum body to resist corrosion and shed heat quickly, along with a 5/8″ hard-chrome shaft and durable seals, they’re designed to deliver reliable performance in any environment.
To complete the system, this kit includes extended sway bar end links, a 2″ rear lift block, bump stop spacers, and brake line brackets—everything required to properly raise your Super Duty without cutting corners. Each component is engineered to maintain correct suspension geometry, braking performance, and overall drivability, ensuring your truck gains the height and clearance you want without sacrificing safety, handling, or ride quality.
