shock length is what actually determines the bumpstop height, followed by tire size if they aren't enough.
the 32's usually only need 1" stops. the 2" should take care of the track bar contact.

say you have 25.5" long shocks (fully extended), 2.5" lift and 32's.... you need 2" bumpstops, even though the tire clearance is good with 1" stops because the shocks bottom out with 1" stops before the bumpstops stops contact the axle.


the easiest way to find out is to remove both front springs and drop the frame on the axles, you can raise and lower the frame to determine where and when contact is made...
flexing will prodce different results and may not even hit due to one side drooped and the other fully/partially stuffed.
a speed bump stuffs both tires at the same time and jams/rebounds the control arm bushings.... something esle, how are your control arm bushings?

lol, yep, but I didn't look at your profile to see if you stated what control arms you have... the stock ones can end up with quite abit of slop when they get worn out.

non adjustable skyjacker's are a 1/4' longer than the stock arms if memory serves... 16" vs. 15 3/4"

yup my stock track bar rubs the Riddler diff cover in the exact same spot.

maybe adjustable lower and upper control arms and move the axle back 1/4"? other than that...i think we'll have to heat up the bar and dent it, then weld some support on the backside.

Looks like you do need to back it off, and also you may want adjustable uppers so you can fine tune it all...caster, pinion angle, axle position (wheelbase). The right settings may be a compromise, but will eliminate your rubbing.
