The fronts are the same as the XJ, of course. The rears that I had are the exact length of the stock rear XJ, so, I made up bar-pin eliminators and installed the 4 4600s on the XJ yesterday.
I had the mid-line Gabriels on the XJ and the ride was harsh, real harsh, and I found out why. The springs are shot on the XJ, now the ride is way too soft, spongy, terrible.
Point is, I'm realizing how the spring and shock work together and one cannot compensate for the other.
Well, new springs on the XJ now........never ends.
