Fabtech K1161M 6" RTS Lift Kit for 20-21 Silverado/Sierra 3500 HD

When you're ready to run 37 in. tires on your Raptor and have the ultimate shock system to go with it then this is the kit for you. The lift features heavy duty ductile iron steering knuckles designed to handle 37 in. tall tires with the vehicle's ESC (electronic stability control) and Traction Control. Typically, 37 in. tires will cause steering and brake issues on the factory Ford steering knuckles. Fabtech knuckles are designed for the oversized tires and will provide years of trouble free service. The lower Raptor control arms are relocated with 1/4 in. thick steel Crossmembers and comes with a 1/4 in. thick steel differential skid plate. To keep the front CV angles proper with the new ride height, the front differential is relocated down between the crossmembers for smooth 4WD operation. The front Raptor shocks are replaced with Dirt Logic 3.0 Coilovers that feature a remote reservoir compression adjuster. This allows for a compliant highway ride with the ability to adjust the compression damping for aggressive offroad use. The rear Dirt Logic 3.0 Bypass shocks allow for 12 in. of wheel travel with two compression adjusters and one rebound adjuster for total damping control. The Dirt Logic 3.0 shocks will provide a noticeable increase in damping for Raptor owners looking to take their vehicle to the next level in suspension performance.
