I have to say that if you have not tried a stock set-up (in good repair)
and then a good coil over/R&P setup (HDK in my experience) then you
are not qualified to comment on what is a revelation in steering and
handling improvement.
There is just simply no comparison. I'm not talking "a little better" but
more like "not even on the same planet" differences.
Not to mention that a stock K seems to lean, even with a factory sway
bar, more than a good riding coil over setup does without the sway bar
even hooked up.
No matter how good the original steering could be (properly adjusted,
no slop in the components etc), the R&P steering is leaps and bounds
better. Comparable to a new modern car.
