Compete Off-Road Suspension System for Super Dutys

If you're looking to lift your 2023-2025 F250 or F350 without sacrificing ride quality or handling, the ReadyLift 4-Inch Coil Spring Lift Kit w/ Falcon Max 3.3 Shocks is one of the best options on the market. This kit is designed to increase ground clearance, improve suspension geometry, and allow for up to 37-inch tires, all while keeping your Super Duty truck driving smoothly on and off the road. It's a complete, bolt-on lift that maintains factory drivability while giving your truck a more aggressive stance and improved off-road capability. This 4-inch lift is often considered the "sweet spot" for Super Duty trucks. It gives you enough height to fit up to 37-inch tires on 9-inch wide wheels with a +18 offset, while still maintaining a comfortable ride and everyday drivability. The increased ground clearance means you can tackle rough terrain, deep ruts, and uneven job sites without worrying about scraping your undercarriage. It also improves approach angles, making it easier to clear obstacles when off-roading.

Falcon Max 3.3 Shocks

The biggest standout feature in this kit is the Falcon Max 3.3 piggyback reservoir shocks. These shocks are performance-tuned specifically for Super Duty trucks, providing adjustable damping that lets you fine-tune your ride based on the terrain. With a 3-position Fast Adjust Knob, you can quickly switch between Soft, Custom, and Firm compression settings. The Soft mode allows a more comfortable, cushioned ride for everyday driving. The Custom setting lets you dial in a balanced feel for mixed terrain. And the Firm mode stiffens everything up for towing, hauling, or aggressive off-road driving. What really makes these shocks impressive is the 8-position Micro Adjust Dial, which gives you an added level of fine-tuning to match your specific driving style. The piggyback reservoir design increases the nitrogen-to-oil ratio, keeping the shocks from fading under heavy use or extreme temperatures. Whether you’re driving in freezing cold or scorching heat, the Red Line high VI shock oil ensures smooth and consistent performance. Plus, the 6061-T6 aluminum shock body resists corrosion and provides increased oil volume for longer-lasting damping and better impact resistance.

Heavy-Duty Tubular Radius Arms & Included Track Bar

Lifting a Super Duty truck means adjusting the front suspension geometry, and that’s exactly what the included tubular radius arms do. These high-strength steel arms are built tougher than factory arms, ensuring they can handle the added stress of a lifted setup. Unlike stock radius arms, these are formed inward, allowing for better tire clearance–a key factor when running 37-inch tires. They also help correct the caster angle, ensuring that your truck tracks straight and doesn’t suffer from wandering or unstable steering. The Falcon Dual Steering Stabilizer included in this kit also helps eliminate those problems by reducing front-end vibrations and improving handling stability. Whether you’re cruising down the highway or navigating off-road trails, this stabilizer setup keeps the steering tight, responsive, and predictable.

Straightforward Install

This is a bolt-on lift kit, meaning no cutting, welding, or major modifications are needed. Everything is designed to work with the factory frame and suspension mounts, making installation straightforward for a professional or an experienced DIYer. Once installed, you'll immediately notice a higher ride height, improved stability, and a more commanding presence on the road. The ReadyLift 4-Inch Coil Spring Lift Kit w/ Falcon Max 3.3 Shocks is more than just a way to raise your truck–it's a carefully engineered suspension upgrade designed to enhance both on-road comfort and off-road capability.
