ReadyLIFT introduces a new 9-inch lift kit the 44-3491 for 2014-2018 Chevy Silverado and GMC Sierra 1500 trucks compatible with both standard and front MagneRide suspension systems. This kit suitable for trucks with the factory Forged Steel front suspension features new tubular upper control arms. It preserves the factory turning radius minimally increases track width by less than 0.5" per side and accommodates up to a 37" tire on a 9" wide wheel with -12 offset. The kit includes a "clam-shell" style lower strut extension that maintains the use of factory struts and avoids strut rotation. These brackets use TCT lower bushings for a precise pivot point ensuring the factory ride quality. The new tubular upper control arms with TCT pivot bushings provide enhanced strength compared to OE stamped steel arms. The kit's front and rear cross members as well as the full-width front skid plate are made from robust 3/16" plate steel. It also features a 1/4-inch boxed plate steel differential drop brackets with double gusset and boxed center rib to handle front differential torsional twisting. The rear lift is achieved with a rear add-a-leaf spring and 3/16-inch thick plate steel rear lift blocks with built-in bump stop landings and an offset pin design to correctly center the axle. The lift blocks are angled to maintain proper pinion angle. Included are premium extended length Bilstein rear shocks. Note: Suitable for 2WD or 4WD models only not AWD. It fits up to a 37" tall off-road tire with specified wheel dimensions. Minor trimming may be required for some aggressive tires. Not recommended for GMC Denali 1500 with REAR MagneRide or models with Rear MagneRide. Front MagneRide compatibility only. Comes with ReadyLIFT ReadyGuard Powertrain Warranty.
