The JKS JSPEC suspension package is the ultimate dual purpose suspension for a JLU owner who wants to have a daily driven and weekend wheeled Jeep. JKS has developed the 3.5" J-Rated system giving you that extra boost out on the trails and with clearance for 35" tires. JKS gives you two options with this kit. First being the standard dual rate springs offering smooth, predictable performance and (HD) Heavy Duty dual rate coil springs specially designed for JLs outfitted with winch bumpers, racks and loaded down with other gear. The HD springs net roughly 1/2" more lift than the standard springs and are designed for extra load capacity. Pairing to these coil springs are the Jspec gas charged twin tube shocks.
