You would probably get a lot more input if you put this question in the Suspension, Steering & Chassis Forum.
For myself, I was all set to do just Teraflex spacers until I discovered one of the spacers was broken. I went ahead and ordered the Mopar lift kit off Amazon.
I havenāt ridden in a JT with anything other than a mopar.(my own) the ride seems similar to stock but a touch more firm, in a good way. Less body roll it seems. Iām very pleased.
