This air helper spring kit is engineered to restore and maintain proper ride height on compatible GMC Yukon and Cadillac Escalade models, enhancing suspension performance under load. Crafted from improved polyurethane, the springs offer excellent anti-fatigue ability and reliable operation across a broad temperature range from -40C to 82C. The kit supports up to 2,300 lbs of load capacity, with manually adjustable air pressure from 5 psi to 50 psi for even load distribution. Designed for direct installation inside coil springs, the components measure 255 mm in height and 123 mm to 128 mm in diameter. Each spring undergoes 100% air tightness testing and has been verified through more than 3,000,000 cycles without abnormal sound or peeling. The complete kit includes two air springs and an air line. By improving handling, braking, and overall driving dynamics, this suspension upgrade helps reduce tire wear and keeps headlights aimed correctly.
