    So, just out of curiosity, if I install a 3.5-4in lift now and didnt wheel until I replaced the driveshafts, is that going to cause damage right away or is okay to take these steps in stages?

    No, it won’t cause any issue with the driveshaft as long as you lower the transfer case or install a SYE and CV driveshaft.

    It's the vibrations that cause damage, so you will need to eliminate them. As @Chris stated above, SYE and CV driveshaft or lower the TC skid until the vibrations disappear.

    Worth adding as well is that a 1” MML will help with the driveshaft angle and likely require a lot less transfer case drop.

    Has anyone added better shocks to the Skyjacker 4" lift? The ride does not bother me too much but I know it could be much better, My wife had a JKU Rubicon with Teraflex lift and Fox reservoir shocks and it was pretty awesome. Just wondering what shocks work well with the Skyjacker lift. Thanks!

    Can't comment for every setup, but most like Fox Shocks with a heavier Jeep, like a JKU. For our lighter TJ's, a shock like the Rancho 5000X runs well. The Fox (and this is subjective), is too harsh for most TJ owners. Rancho 5000X found here. I think the $50 rebate is still available. They will work well with your Teraflex lift.

    If you want the smoothest ride you will get on a TJ, it's going to be the Rancho RS5000X or RS9000 shocks.

    So far I've run OME Nitrochargers, Bilstein 5100s, Fox 2.0s, and Rancho RS5000X shocks. The Ranchos blow the others away in terms of ride quality. There's not even a question about it.

    Those Fox shocks will ride good on a JKU, because it's much larger and heavier. They ride very poorly on a TJ though in my opinion, as they are much too stuff.

    Any recommendations on a 1-1.25 in body lift kit? There’s so many I’m not sure what the best option is. I have a 2.5 in lift on my 04 TJ and want to run 33’s. Also if someone could explain bump stop to me. What is it. How is it installed(pix would help) and how do I determine how much I need?

    Honestly, they're just pucks to lift the body, so you really can't go wrong with any brand.

    A few common ones that people often run are:

    JKS 1.25" body lift
    Rough Country 1.25" body lift
    Daystar 1" body lift

    You can't go wrong with any of those.

    Bump stops are on the inside of the spring. They keep the spring from being collapsed all the way. The factory foam bump stops are on the top spring perch, and contact the bottom perch if the axle moves all the way up. Longer springs require bump stop spacers of some sort, in order to not destroy your shock absorbers, and keep your tires from messing up your fenders, basically.

    Read this, it's very, very informative:
    How to set your bump stop on a Jeep Wrangler TJ

    In a nutshell though, your bump stops are what keeps your wheel / tire from hitting your fender, as well as other components (i.e. track bars, steering, etc.) from bottom out or hitting each other.

    Think of it this way... If you put a 4" lift on your TJ with larder 33" tires and don't bother to add more bump stop, you're going to crush your fenders the first time you try to flex it off-road, and you're likely going to crush other components as well, such as track bars hitting the diff cover, etc.
