Durable Helper Spring Kit by ReadyLift Air

Enhance the towing and hauling capabilities of your 2017-2022 Ford F250/F350 with the ReadyLift Air Load Leveling Helper Spring Kit, designed to optimize load handling and improve your driving experience. The ReadyLift Air kit features two air springs per side, which work in unison to prevent the rear end of your truck from sagging and swaying under heavy loads. This is particularly useful for maintaining vehicle stability and control when you're towing or hauling substantial weights. The air springs are rated to support up to 7200 lbs at 150 PSI, ensuring robust load leveling capacity without exceeding the manufacturer’s recommended Gross Vehicle Weight Rating. One of the standout features of this kit is the LOGIQ Sleeve Style Air Bags, which are set at a 1.6Hz natural frequency. This specification provides a smoother ride compared to traditional double bellow air springs, which typically have a higher natural frequency closer to that of race car stiffness. This lower frequency results in less vibration and a more comfortable ride, making it ideal for both daily driving and heavy-duty applications.

Premium Construction & Design

Adjustability is a key component of the ReadyLift Air Helper Spring Kit. With adjustable air pressure from 10 to 150 PSI, you can manually adjust the ride firmness to suit your specific needs. This gives you the versatility to tackle any job with more confidence knowing you remain in control. Installation is both straightforward and efficient, thanks to the kit being 100% pre-assembled in the box. The no-drill, clamp-around design of the brackets cuts installation time in half, allowing for a hassle-free setup that gets you back on the road quickly. Better yet, the heavy-duty custom-fit brackets ensure a secure and precise fit that aligns perfectly with your truck’s factory frame and leaf spring locations. ReadyLift Air is so confident you'll love their product, they back this kit with a Limited Lifetime Warranty to help keep your investment protected.
