    Hyperco Composite Leaf Springs are significantly lighter than steel, retain their design arch, and provide more side bite off the corner. The Hyperco CLS is truly a cost effective, high performance alternative to steel. It allows teams running leaf springs to be consistent night after night without having to constantly measure, monitor and change their springs for loss of arch / sagging. The initial cost is a value based on the incredible service life. Leave the steel on the street, hook up with the Hyperco CLS performance advantage.

    • On average 70% lighter than steel
    • No sagging or chassis inconsistency
    • More durable = greater value
    • Quicker off the corner compared to steel springs
