This would be my guess. Otherwise, make sure they got the right shocks. Also, did you get an alignment after the lift? I don't think that would make it bumpy, but might handle funny.

I had this lift with Bilsteins installed a week ago and it's definitely riding better than stock. There are dips and speed bumps that I used to slow down for that I can take much faster now that I have this lift and shocks. Mine is a 2012 JKU Sport and you mentioned in the OP that you have the 2 door, so might be different springs and/or shocks. Plus, I have 33's so not sure if that would make a difference.

 

I run the same set up except on 37s
I agree very stiff, Mine seems to be getting softer or im getting used to it ran the tires at 18psi so i know it was not the tire pressure. I am switching to coils to evo plush coils see if that helps.

 

37s on a 2.5, are you running flats and did you have to cut up anything to make it work?

 

Got pics?? I'm debating these tires but don't know if I can accept the lack of aggressive looks.

 

I am also running a 1.25" body lift and cut my factory flares 2" bump stops front and rear tires measure out when new 36.75". My old 09 i ran 37s on a 2.5" lift but had to trim the rear wheel wells just folded over the pinch seem.

 

Mine tracks fine, everything lines up front to back and side to side. The shop that did the lift really knew their stuff. It's just really, really set up stiff. If there any ex/current motocrossers, it's the difference between an outdoor set up and a supercross set up!

Here are some pics yes the shocks are the correct ones. It isn't really a bad stiff kinda a very controlled stiff think BMW M3 kinda stiff. I do a lot of highway driving and it gets a little rough over a trip. I wasn't sure about the tire either but once you get to the 12.5" wide they look aggressive enough for me plus they are very quiet.





I know the wheels in the second pic are black I have been debating painting them so the wheels are Photoshopped black

 

You may have just sold me. I'll be going 35x12.50 with black wheels AND I have a red rock 4 door. Sorry to copy your style!

 

Sounds good to me mine is Deep Cherry Red Pearl so they wont be the same

Depending on what you have for extra weight front and rear you may need to add some spacers. Between rear bumper/carrier & spare, gas tank skid and hard top for the winter I need about 3/4" to an 1" on the passenger side and 1/2" to 3/4" on driver side. You can see what I mean below - I have the spacers to put in, just been lazy.





can see the need for a rear spacer..
