The Hellwig Contact Helper Spring kit for 2020–2021 Chevrolet Silverado/Sierra 3500HD pickups (SRW) adds two additional leaves to factory contact overload springs to provide earlier support as loads increase. When the helper engages it stiffens the overload assembly, reducing sag and improving level-load carrying capacity while leaving normal unloaded ride behavior unchanged. The kit mounts to factory contact springs for straightforward installation.
