    This Hellwig contact helper spring adds extra level load capacity to the 20-21 Chevy Silv 3500HD 2/4WD, giving better support and less sag under heavy loads. As the truck is loaded, the added Hellwig leaves contact the factory overload springs sooner to stiffen them and reduce sag, and in normal unloaded use ride quality stays the same. It mounts directly to the factory contact springs for an easy bolt-on install.

    • Type: contact (overload) helper spring
    • Adds: 2 additional leaf/leaves
    • Install: bolts directly to the factory contact/overload springs, no U-bolts required
    • Normal use: ride quality unchanged until the springs make contact under load
    • Warranty: Hellwig limited lifetime warranty
    • Part number: HWG9703

    FAQ

    How much support does it add?

    It adds level load capacity so the truck carries and tows more comfortably.

    How does a contact helper spring work?

    As the truck is loaded, the added leaves contact the factory overload springs sooner, stiffening them and reducing sag.

    Does it change the ride when empty?

    No. In normal unloaded use ride quality stays the same; the extra support engages only under load.

    Is it a bolt-on install?

    Yes. It mounts directly to the factory contact springs.

    Is it warrantied?

    Yes. It is backed by Hellwig's limited lifetime warranty.
