Faster Installation – No drilling required… Simple “clamp around” bracket designs combined with 100% pre-assembly cuts installation time in half!

5th Wheel Hitch Integration – See below  5th wheel hitch compatibility.

Precision Fitment – Built-in features that locate off the factory frame and leaf spring locations guarantee proper fitment, geometry, and operation for every install. 

Properly Scaled to Match the Size of Your Truck – Rather than using the archaic “one-size-fits-all” approach, ReadyAIR properly scales the air spring size and quantity to truly maximize your specific truck’s towing and hauling capability. 

Improved Ride Quality, Stability, and Load Support – Competitor double-bellow style air springs have a natural frequency of ~2.5Hz (close to race car stiffness). LOGIQ Air Springs have a 1.6Hz natural frequency to ensure that you will feel the difference. 

More Suspension Travel – Competitors limit the factory travel and typically eliminate the OE bump stops. ReadyAIR kits have improved suspension travel and retain the factory bump stops for optimal suspension performance.

Lifetime Warranty – All ReadyAIR suspension kits come with a Limited Lifetime Warranty and a FREE ReadyGUARD 5-year – 60,000 mile Powertrain Warranty. 

Application Notes: 

For use with trucks equipped with factory overload springs ONLY. Not for use with or cab & chassis model trucks. Not compatible with most aftermarket leaf springs.

Not Compatible with 2022-23 Dual Rear Wheel Trucks due to unique bump stop configurations.
