NEW 2009 model super duty knuckles.
these knuckles will fit all 2005-2012 super duty axles and Cs. In 2012.5 the brakes changed but the knuckle dimensions are the same. There have been various minor changes in the knuckle design over the years but the overall dimensions remain the same. These knuckles are new, not reman, and come with new ball joints.
If you are building an axle these are a great choice. these knuckles will accept bigger axle shafts than the older kingpin style knuckles. Kingpin knuckles will accept a maximum u-joint size of 1480 but these knuckles will accept a 1550 size u-joint or a big bell RCV!! Add a set of ball joint eliminators and these knuckles become stronger than older kingpin knuckles!
If you are building an axle check out our inner C package, unit bearings, and weld-on high steer arms.
