Pro Comp is proud to announce that its 4-inch suspension system for the 2016 - 2018 Silverado & Sierra 1500 has been tested and successfully passed the Federal Motor Vehicle Safety Standard (FMVSS 126) test. This highly specialized test was performed to show that the installation of a Pro Comp 4-inch suspension system, Pro Comp wheels and 33-inch Pro Comp Tires would not compromise the performance and effectiveness of the vehicle's Electronic Stability Control system.

Starting with the 2014 Silverado and Sierra there are now three different types of suspension configurations. Please make sure you verify your vehicles factory suspension material type before purchasing or installing your Pro Comp suspension system. This lift will ONLY FIT the Stamped Steel suspension equipped trucks.
