ReadyLIFT introduces a 9-inch big lift kit for 2014-2018 Chevy Silverado and GMC Sierra 1500 trucks, compatible with trucks with or without front MagneRide. The 44-3490 kit is suitable for GM 1500 trucks with Aluminum or Stamped Steel front suspension, featuring new tubular upper control arms. It maintains the factory turning radius, with minimal track width increase of less than 0.5" per side. The kit accommodates up to a 37" tall tire on a 9-inch wide wheel with -12 offset. It includes a "clam-shell" style lower strut extension, which retains the use of factory struts and doesn't require strut rotation. These extensions use TCT lower bushings for a precise pivot point, maintaining the factory ride. The kit's tubular upper control arms with TCT pivot bushings offer enhanced strength over OE stamped steel control arms. It features boxed steel front/rear cross members and a full-width front skid plate made of 3/16" plate steel, compatible with the OE front plastic gravel guard for engine protection and airflow maintenance. The kit includes 1/4-inch boxed plate steel differential drop brackets with a double gusset and boxed center rib, supporting front differential torsional twisting. Suitable for 2WD or 4WD applications (excluding AWD), it offers rear lift with an add-a-leaf spring and 3/16-inch thick plate steel rear lift blocks with built-in bump stop landings and offset pin design for axle centering and proper pinion angle. Premium extended length Bilstein rear shocks are included. Note: Fits up to a 37" tall off-road tire requiring a 9-inch wide wheel with -12 offset (minor trimming may be needed for some tires). Not for AWD, GMC Denali 1500 with REAR MagneRide, or models with Rear MagneRide. Compatible only with Front MagneRide and factory Aluminum front suspension. Comes with ReadyLIFT ReadyGuard Powertrain Warranty.
