Prepare yourself for the perfect combination of off road performance and on road handling. This 4" ZJ system offers dramatic improvement in wheel travel and performance. The new massive lower control arms drastically increase the strength over stock, are formed to clear the mount for more wheel travel and correct front alignment. These arms feature rubber bushings to absorb the road and offer a degree of flexibility. This system comes with a transfer case drop as well as rear pinion cam locks that rotate the rear pinion for proper driveline angles. With 4" of lift, you can clear up to a 32" tire with room to twist as well as use your Jeep for a daily driver.
