Description
Heavy-Duty Stability for the Long Haul
When you’re operating a 2500HD or 3500HD, your suspension faces extreme pressure. The Retrue Air Helper Spring Kit is designed to support your factory leaf springs by adding a secondary layer of air-cushioned support. By increasing the spring rate, it effectively minimizes road shock, vibration, and “swaying,” ensuring your truck stays level and safe under maximum GVWR (Gross Vehicle Weight Rating).
