Product Summary

The ALC57211 LoadLifter 5000 Air Spring Kit is designed specifically for 2014–2018 Chevy Silverado 1500 and GMC Sierra 1500 pickups. Built to tackle heavy-duty towing and hauling, this rear suspension upgrade provides serious support where it counts. Whether you're pulling a camper, carrying heavy equipment, or transporting landscaping materials, the LoadLifter 5000 eliminates sag, improves steering response, and helps preserve your truck’s suspension geometry under stress. These premium air springs are fully adjustable from 5 to 100 PSI, allowing you to fine-tune rear height and ride stiffness based on the load. The system delivers up to 5,000 lbs of leveling capability, reducing trailer sway, enhancing braking, and increasing control when cornering. Crafted with reinforced rubber bellows and weather-resistant hardware, the kit is built to handle harsh road conditions and challenging work environments. Installation is designed to be straightforward with custom-fit brackets and minimal drilling required. It's also compatible with Air Lift’s suite of onboard air management systems for real-time load control. Whether for personal use or work, the ALC57211 delivers unmatched performance, comfort, and confidence when your Silverado or Sierra 1500 is under load.
