The JLU rocker panel is wider than the JKU's and lacks the supporting structure inside, so a body mount can take a hit and still leave the body bent. The Billy Rocker for the 4-door JL avoids that by mounting to the frame. A steel and aluminum space frame carries the load, an aluminum skin covers it, and the skin can be replaced after damage. The pair aligns to factory holes and works with or without Titan Tub Armor.
