Fabtech K1055M 3.5" UCA Lift Kit w/Shocks for 11-19 Silv/Sierra 2500HD/3500

Our 3.5” System provides less lift than our 6” RTS™ system but still allows use of 33” or 35” tall tires with cutting for street and offroad use. We have developed this system utilizing replacement upper control arms constructed of 1.50” OD .120” thick wall DOM tubing that attaches to heavy duty Fabtech ductile iron steering knuckles. The factory torsion bars remain in the stock position and use new forged adjusting keys to provide the proper amount of lift. Upper Control Arms Built With Same Materials Found On Trophy Trucks .120? Wall 4130 Chromoly Tubing. 1.50? OD .250? wall DOM Bushing Barrels Extended Range Ball Joints Ductile Iron Steering Knuckles
