This design keeps the torsion bars in their stock location rather than hanging lower under the chassis.
The Cognito 110-P0778 4” Standard Lift Package With Fox Shocks increases the front track width by 5/8" per side to maintain proper caster settings and the incorporated a front skid plate protects the front differential that ties the included front & rear cross members together for added strength. This lift kit comes with the Cognito Pitman and Idler Arm Support Kit that corrects a design defect in GM truck steering systems and add rigidity to the steering components. With Fox shocks to give you smooth ride on the street and responsive handling off-road and a complete hardware kit, this American made lift kit includes everything you need for installation.
