This high quality 6" system retains the factory track width keeping the tires under the fenders for a clean appearance. It has been designed to clear 33" tall tires while providing a factory like ride quality. Heavy duty 1/4" thick steel lower control arm Crossmembers provide superior ground clearance while the integrated front differential Skid Plate adds protection to the drivetrain. The front differential is relocated in a manner to reduce driveline vibration when in 4 wheel drive mode at highway speeds. The system utilizes a simplistic upper Coilover spacer that does not require the disassembly of the shock for a quick installation. The factory rear shocks are retained with extended length mounts. Fabtech?s rear Coil Springs provide increased ride height with a comfortable highway ride. New upper and lower rear Link Arms re-positions the differential to the precise pinion angle to eliminate driveline vibration at all speeds. Rear extended length Sway Bar Links and heavy duty Track Bar Bracket retains the proper roll center of the vehicle for both on and offroad use. This system passes FMVSS 126 standards for stability control functionality as tested by an independent lab. All systems come with a Free 5 year 60,000 mile Powertrain Warranty. 6in.
