Extreme Duty 4.5 Inch Long Arm System by Rubicon Express

The RE73XX 3.5-5.5 Extreme Duty Long Arm System is the first and only radius long arm suspension available for the Jeep JK. This kit features our world class chromolly radius arm both in the front and now in the rear. Geometry has been meticulously engineered to keep pinion and driveshaft angles in phase, while eliminating jacking and unwanted suspension squat. Engineered radius arm suspension with properly valved Rubicon shocks correctly allows the JK to transmit throttle input to the wheels and over varied terrain, providing forward progress instead of getting stopped due to unwanted compression response. This suspension will allow the use of 37 inch tires.
