JLU 4.5 Inch X Factor Pro Elite "No Limits" Aluminum System w/ PB+J Lower Mid Arms 392 Model

The Rock Krawler 4.5" X-Factor PRO ELITE "No Limits" Mid-Arm 392 System is specifically designed for 392 Rubicon owners who want a complete system, bolt-in installation, and the best articulation of any MID-ARM kit on the market. The lower control arms are our signature PB+J (Pure Beef and Jealousy) mid-arms machined from 2” x 3” billet 7075 Aluminum. All 4 other control arms are machined from round 7075 Aluminum and come with the benefits of X-Factor built right in. Our system proves its durability and off-road performance every time you hit the streets or trail! Our industry leading, X-Factor Series, adjustable upper and lower control arms offer a total of 95 degrees of misalignment when paired with our Pro-X Krawler Joints and Adventure Series joints. The inherent bind in a factory JLU control arm is greatly reduced. Our maintenance free "Adventure Series" joints are found in your front and rear control arms at the frame connection, while our "PRO Krawler Joints" tie in your axle connections. With so much adjustability, it allows you to precision tune the JLU's caster and pinion angle front and rear. The “No Limits” front sway bar end links pair amazingly well with the factory Rubicon E Disconnect ensuring bind free suspension travel in the roughest of terrains.
