I have not test fitted that, but that is what I gathered from other builds that I have been following. I have a set of LX and a set of Jeep, the jeep ones seem to flow down more and look to be no issues with the stock K and torsion bars. Johnparts did a test fit in his build before swapping to an HDK.
