Fabtech 10-14 Ford Raptor 4WD 4in Alum. UCA System w/DL 3.0 Resi Coilover & Rear DL 3.0 Bypass Shock

When you're ready to run 37in 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 37in tall tires with the vehicle's ESC (electronic stability control) and Traction Control. Typically, 37in 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 1/4in thick steel Crossmembers and comes with a 1/4in 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. Fabtech's Billet Aluminum Upper Control Arms replace the factory weak ball joint arms for severe offroad use with superior construction and awesome looks. The Billet UCA feature 1.25 Stainless Uniballs and 3/4in heims at the frame for rock solid suspension performance. 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 12in 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. FRONT DIRT LOGIC 3.0 RESI COILOVER: These race quality Coilovers directly replace the stock Raptor Coilovers with improved offroad damping for aggressive driving in the most punishing conditions. They provide an additional 10% of wheel travel for a total of 11in when used with uniball upper control arms.
