I am redoing my kit. front has a spacer and rear has a block. I ordered some shocks from DSMS, but we had a different idea for the rear. The rear or my truck was topping out pretty easily, even with only a 1" block. Marco said they had been experimenting with 5100s for the front of a jeep TJ, as they are 24.6" long and the valving seemed better on the reg cab.
I got them friday and installed the rears today- the ride is badass, and I got good flex. i might order new lines if I go offroad more, but for now its just fine. I am going to throw the fronts on this week when I get time. But overall it worked out awesome.
Marco also said that since I got the 4cyl reg cab and its new- I will be just above 2" at that 1.75 setting, which is perfect. Apparently thats why the instructions say "average lift" at the various settings.
Once its all finished up I will post a photo, since I have never posted one of it in any shape or form.
