ZR2 Front Jounce Shock System
The Chevrolet Performance ZR2 Front Jounce Shock System, designed specifically for 2017+ Colorado ZR2 models, is a nitrogencharged hydraulic secondary suspension bump shock intended exclusively 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.
NOTE: Intended for off-road use.
