With an 11.31” top and a 10.13” bottom, this dual-top suspension spring ensures even weight distribution, reducing strain on suspension components while improving overall vehicle stability. Trucks carry heavy loads over long distances, making suspension integrity critical. A high-quality air suspension system extends the life of tires, minimizes wear on axles, and enhances driver comfort, especially on uneven terrain. The Hendrickson S-20901 is a must-have for fleets that prioritize efficiency and long-term vehicle performance.
