Towing a trailer or hauling a heavy load and your truck’s sagging in the back? These maXpeedingrods Air Helper Springs are here to save the day. They slide right inside your existing rear coil springs and give you up to 2,300 lbs of extra load support. You can adjust the air pressure from 5 to 50 PSI depending on your load—just add air when you’re hauling, let some out when you’re empty. It helps eliminate that annoying rear-end squat, stops your vehicle from bottoming out, and seriously cuts down on trailer sway. Made from tough, elastic polyurethane so they last. Fitment is super broad: works for Chevy Tahoe, Suburban, and Avalanche 1500 (2000–2020), GMC Yukon/Yukon XL (2000–2020), Cadillac Escalade (2002–2007), Ford Country Squire (1987–1991), and Hummer H2 (2003–2009). Installation is straightforward—no major mods, they tuck inside the coils. Comes with a 1-year warranty against defects and lifetime technical support. If you’re tired of your ride sagging or swaying under load, this kit is a game-changer for leveling things out and getting back a smooth, controlled drive.
