2024-2026 Duramax LoadLifter 5000 Ultimate Air Spring Kit with Air Spring Cradles (88408)

This LoadLifter 5000 Ultimate kit is purpose-built for the off-road-focused 2500HD Duramax (Silverado ZR2 and Sierra AT4X), adding up to 5,000 lbs of rear load-leveling capacity for confident towing and hauling. Fully adjustable air springs from 5 to 100 PSI eliminate squat, trailer sway, and body roll while keeping braking and steering control sharp. Included Air Spring Cradles let the springs detach from the lower bracket for full suspension extension, making it ideal for overlanding and off-roading, and the internal jounce bumper absorbs shock at any pressure.
