Well, my 2 1/2" Skyjacker Double Flex kit came with the fully
adjustable control arms with heim joints at both ends. The
installer didn't really know what he was doing I think, as he left
the front axle as far forward as it could possibly go, and the axle
off center by a good 2 inches (I had the DT track bar installed at
the same time). I got the truck up on 12 ton jack stands and
readjusted the track bar and control arms myself until things
were as centered as I could get them. I didn't measure them
afterwards, so I can't say what they currently are exactly.
