Synergy Jeep JK 3 Inch Lift Stage 4 Long Arm Suspension System is for those wanting maximum performance and capability without sacrificing ride quality. It carries over the quality components of the Stage 3 System, but improves upon them by swapping out the Standard Length Control Arms for Adjustable Long Arms and Long Arm Mounting Brackets. This is a 100 percent bolt on system with no welding required. This system will fit 35 inch tires with stock fenders or 37 inch tires with high fenders.
