# Zone Offroad 11-15 GM HD Shock Extension

Did you install a Zone 2" torsion bar key leveling kit on your 2500HD and 3500 pickup truck and now your shocks are too short? Use these in conjunction with your factory shocks, and avoid having to spend double the price on a set of new shocks. These spacers install on the top factory shock studs to extend the length of the shocks. This allows for added droop travel required once a leveling kit has been installed.

-   Extends upper shock mounting to allow full suspension travel with 2" torsion bar keys installed
