The Chevrolet Performance ZR2 Front Jounce Shock System, designed specifically for 2017+ Colorado ZR2 models is a nitrogen charged hydraulic secondary suspension bump shock intended for off-road use.  The Jounce Shock System greatly enhances gross vehicle motion control, increases suspension bump capacity, and provides exponential bottoming protection for extreme off-road conditions.

This complete bolt-on system (requires removal of existing jounce bumper and bracket on frame) includes both front Jounce Shocks, required mounting brackets, and all required fasteners.
