88-21090 | ReadyAir Rear Load Leveling Helper Spring Kit (2009-2014 F150)

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.

Application Notes:
Not compatible with most aftermarket leaf springs.

Faster Installation - No drilling required... Simple “clamp around” bracket designs combined with 100% pre-assembly cuts installation time in half!
5th Wheel Hitch Integration - Not compatible with 5th wheel hitches with the frame clamping system.
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.
