Upgrade your 4-Door Jeep Wrangler JL with a 3.5" J-Kontrol suspension system giving excellent stability on and off road. Building off of the J-Venture systems designed for equal parts on-road handling and off-road capability, the J-Kontrol system adds in front control arm correction brackets. These brackets further enhance the on-road handling by flattening out the control arm to more closely mimic factory angles while correcting caster. Combined with the dual rate coil springs, specially valved gas shocks, adjustable track bar, quicker disconnects and more these systems are very solid for the daily driver or beach cruiser, that is not afraid to get out on the trail and mix it up. Take control with J-Kontrol.
