Stock JK Springs and Shocks on a TJ
The front sripngs will work, but you would lose about 1" in the front compared to the stock front TJ springs. I am basing this off the fact that I gained 1" in the front from the TJ springs when installed in the JK.
The TJ had a heavier engine and so their springs in the front are designed for the extra weight. They aren't any taller, but the heavier springs will more than compensate for the added weight of a bumper and winch.
