16. Both upper and lower control arms mount on the same bracket. The four-link easily cycled more than 14 inches of movement without shocks, steering, and a track bar hooked up, but we'll be limiting this XJ's front travel to 10 inches with some 10-inch-stroke shocks and properly placed bumpstops. Without modifying the shock mounts we couldn't get any longer of a shock in with a 4.5-inch lift. Besides that, the track bar and steering linkage would both have to be modified to allow any more travel than 10 or 11 inches.
