ReadyLIFT is proud to introduce ReadyAIR Performance Load Leveling Suspension powered by LOGIQ. ReadyAIR products bring this 70-year-old market into the 21st century with the latest LOGIQ air spring technology that provides the ultimate blend of ride quality and load stability, in a 100% factory assembled and READY to install package.


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

• OEM Integration - Compatible with OEM and most aftermarket fifth wheel hitches.

• 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.
