Rubicon Express 4.5" Extreme-Duty Long Arm Suspension System for 07-18 Jeep Wrangler JK 2 Door

The RE7344 4.5 inch Extreme-Duty™ Long Arm System is the first and only radius long arm suspension available for the Jeep JK. This system features our world class chromoly radius arm both in the front and in the rear. Geometry has been meticulously engineered to keep pinion and drive shaft angles in phase, while eliminating jacking and unwanted suspension squat. Engineered radius arm suspension 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.

Check out the optional AEV ProCAL Module, a great finishing touch to any lift kit as it can reprogram your vehicles computer compensating for gear ratio and tire size changes after lift kit installation not to mention many other additional features.
