Synergy Jeep JK 4.5 Inch Lift Stage 3 Suspension System includes all the components from the Stage 2 System but exchanges the Fixed Length Lower Control Arms for Adjustable Lower Control Arms (8051, 8052) and adds Adjustable Upper Control Arms (8053, 8054) front and rear. The Adjustable Control Arms are required for locating the front/rear axles with lift heights over 3 inch for adjusting the pinion angles when using aftermarket 1310-1350 drive shafts. This system also adds Front and Rear Adjustable Track Bars for centering the axles under the vehicle at the increased ride height. This system will fit 37 inch tires with stock fenders or 40 inch tires with high fenders.
