Introducing the GMC Sierra 2500 HD Coilover Suspension Kit by Rough Country, designed specifically for the '11-'19 models. This front suspension kit features the high-performance N3 Shocks with a striking metallic silver finish, providing an unmatched driving experience both on and off-road.

Dive deeper into the myriad of features this kit offers, starting with the N3 shocks' 10-stage variable valving, ensuring precise damping control. You'll experience a highway ride that's smooth and controlled, while the confidence of tackling off-road adventures remains intact. The high-pressure nitrogen charge maintains consistent performance, complemented by the robust 18mm chromed hardened piston rod that offers resistance to corrosion and extends the life of your shocks. With a 54mm shock body, heat dissipation is expedited, which effectively prevents shock fade even during the most demanding use. This ensures your Sierra is not only prepared for all-weather conditions, thanks to the military-spec fluid rated to -40 degrees celsius, but also ready to deliver a ride that's as smooth and quiet as it is controlled due to the natural rubber bushings that minimize road noise.
