Keep Your Lifted Truck Level When It Counts Most

If you’ve lifted your truck and rely on air springs to keep things stable, the Air Lift 52440 4-Inch Air Spring Spacers are exactly what you need to get the most out of your suspension. These spacers let you retain the full benefits of your air bags even with added height, helping your truck stay level when you’re hauling a heavy load or towing down the highway. No more sagging rear ends or unpredictable handling, just better balance, better control, and a safer ride. Each spacer locks together with 1-inch composite disks to give you the exact height you need, while the tough molded material ensures long-term durability without adding unnecessary weight. Whether you’re hauling gear to the jobsite or hooking up the fifth wheel for the weekend, these spacers make sure your air springs are doing their job. Best of all, they’re universal and easy to install with most Air Lift systems. If you want a smoother, safer, and more predictable ride in your lifted rig, this simple upgrade makes a big difference.

Designed To Restore Air Spring Function On Lifted Axles

The Air Lift 52440 4-Inch Air Spring Spacers are specifically engineered for lifted truck applications where the axle has moved further from the frame. These molded composite spacers ensure your air springs remain within their optimal operating range, preserving ride quality and load-leveling performance even with suspension modifications. The kit uses 1-inch modular disks that lock together to achieve the correct height spacing, resulting in consistent alignment and function with your existing air bag system. This configuration is ideal for maintaining factory-level performance and safety when towing or hauling with a lifted setup. Each spacer is designed for installation on a single axle and is compatible with most Air Lift air spring kits, although air bags themselves are not included. With these installed, your suspension system maintains its ability to distribute weight evenly, reduce sway, and support heavy loads without strain. It’s a practical solution for truck owners who want to keep their lift and still take full advantage of their air ride system.
