Explorer Procomp Chevrolet Silverado and GMC Sierra 1500 Series 6" Lift Kit # K1159B. Fits 2014, 2015 and 2016 Chevy Silverado 1500 and GMC Sierra 1500 trucks with the Aluminum Suspension only. This 4" Suspension Lift System is engineered to deliver amazing performance both on- and off-road. With 4" inches of suspension lift you can run up to 33" tall tires. With additional height and larger tires your new GM truck will have a more aggressive stance and attitude. This lift is 100% compatible with the factory StabiliTrak electronic stability control system. Pro Comp is proud to announce that its 4-inch suspension system for the 2014 - 2015 - 2016 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 two different types of suspension configurations. One is an Aluminum Suspension package which includes forged aluminum steering knuckles as well as aluminum upper and lower control arms. The other is a steel package which includes cast steel steering knuckles with forged steel upper and lower control arms. The Aluminum suspension components are usually Silver in color. The Steel suspension components are usually Black in color. Another easy test is a Magnet will stick to the steel components and NOT to the Aluminum components. Please make sure you verify your vehicles factory suspension material type before purchasing or installing your Pro Comp suspension system.
