Nice! What gears are you running and hows your gas mileage now? Also could you take a picture of you standing next to it to get an actual perspective of the height?

It has the stock 4.10's in it right now. I haven't really calculated the mileage but it's not to bad. I'll get a picture by it tomorrow. My little sister took it to prom tonight haha!

If you are gonna do 35's I would do 2.5 with flat fenders. You should get more lift I feel like I did with the 3.5.
Love the 37s but Ching Ching !

Damn, that looks nice! I'm waiting to cut my fenders until i get 37's or 40's. It would not look right if i did it now.

Anyone willing to measure ground clearance from ground to transfer case on a 4 dr with either of these lifts?

The reason I ask is because I know what the ground clearance was on my old Heep and know how that handled on the trails I run.

The 4 door and the 3.5 makes a good combination. 2 door and 2.5 makes a good combo.

Depending on your setup, you could see more than 3.5" of lift. If you are running heavy aftermarket bumpers and winches, the 3.5" seems to net about 3.5" (as it did on mine). Very level....no rake. If you have stock bumper in the front, you could see a slight reverse rake as the top few wraps of the progressive coils won't have enough weight to compress. The 3.5" with 35's and stock flares look great. Won;t fit 37's unless you run flat flares. If you are running flats now, the 35's might look a little small.

as for ride vs. stock...there is no way any Jeep rides better than stock when lifted. We drive boxes. Lift that box higher and now you have to deal with geometry issues which can only be corrected to a point. Plus, anytime someone sneezes outside, the box acts as a sail and you will feel it. Especially on the highway. I can do 3 lane changes without touching my wheel sometimes when the wind is blowing. Much worse at 3.5" over my old 2.5" and much much worse over when I was stock.

The tide is still nice and handles bumps well but the fact you are now raisied higher just throws off all the engineering that went into designing the JK in the first place. The best comparison really is how this rides vs other lifts....when people say it rides better than stock, it reminds me of when people say "that cover band played the song better than the original"
