CST Suspension engineers their suspension to provide increased strength, performance, overall ride quality, and allow your truck to perform better than stock with many upgrades.

This 4-6" adjustable lift kit for the 2011-2018 Chevy Silverado / GMC Sierra 2500HD includes gusseted high clearance cross-members with a full size differential skid plate, cast iron CNC machined front steering knuckles, differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake line drop brackets, all necessary install hardware, and O.E. front shock extensions.

SoCal SuperTrucks is proud to help conceptualize this high clearance 4-6" lift kit with CST Suspension by bringing them our 2015 GMC Sierra Denali 2500HD to design the kit around. We wanted a suspension system that will clear larger tires without giving us that massive lifted truck look. The adjustable 4-6" lift kit also has many shock upgrade options to give everyone their desired Chevy truck. Whether you have a 2011, 2012, 2013, 2014, 2015, 2016, 2017 or 2018 Chevy Silverado 2500HD / 3500 or a GMC Sierra 2500HD / 3500 this 4" to 6" High Clearance Lift System by CST Suspension will put a smile on anyones face.
