Okay, I've been researching and looking around, but I still need some help here:

Can you guys point me in the direction of a kit that will bear the weight of the bumpers (and probably a winch), clear 33"s while disco'd, but not be high enough to cause me to need a new rear drive shaft?

What if I get some take off Rubi 4dr springs and shocks and put them on my X, would that do it?

Shipping weight of the bumper is 115 lbs, according to the UPS tracking info.


Thanks,
Jason

Spent the money on BB. Then had to buy coils. My winch weighs 89 lbs, bumper 65 lbs. Check out the weight of the your winch before you buy, come winches weigh upwards of 110 lbs.

Would I need to swap driveshafts if I get the OME HD 2" kit? What about the MD kit?

Just trying to get this sorted out, I'd like to get rid of these stock skinny ass tires soon...

As you'll find there are many options for what you need. As for a 4 door rubi swap, this is what I did, 4 door rubi hd springs/shocks mated with a TF leveling kit (super budget boost). I got a good 2" of lift in the middle, if not a bit more. This is more then enough for my 285/75 cooper stt's on pro comp 7089's, with more then enough room when flexed.

This is with no bumpers/winch, which should level it right out when I get them, but we'll see. I did also get a rear track bar bracket and jks front adj, to put my axles back in line.

Long story short, you can built a little budget boost with someone's rubi take offs, just make sure to get the part numbers to ensure they're taller/stiffer then what you have. And if you don't love it, buy a "real" lift kit.

With coil spring lift be aware that a 2.5" coil lift will give you anywhere between 2.5-4" of lift. I know because I bought a 2.5" Pro-comp.
Yeah, I know, that's why I'm wondering about the Rubi springs. I don't want to have to mess with changing driveshafts or anything, but most 2.5" lifts give 3.5" or more. I'm not going to regear, so 35's won't be in my future. Just 33's. As long as I can clear those with the bumper weight, I'm happy. It's just freakin' confusing looking at all these kits and wondering whether they are complete, how tall they really are, whether I'll need to modify the driveline, etc.

more than likely, you will not need anything in addition to a front track bar, with a 2.5" coil lift (assuming you are 6spd). also, TeraFlex just released 2dr specific coils that will get you closer to the actual lift description. i am running their pre-2dr specific 2.5" coil lift with only a front track bar and using their supplied rear track bar relocation bracket. been smooth as eggs for about a year.

Unfortunately, there is no straight-forward response. The reason most companies don't make a "complete" 2.5in. - 3in. kit is because everyone wants different components at that height and it's not feasible to make a complete kit for everyone. Some companies offer more components in their 3in. kits than others, but it's not until you get into the 4"+ lifts that you get more complete kits since most suspension components are required at that lift height.

I went with the Teraflex 2.5" coil lift with Teraflex 9550 shocks, Teraflex front lower control arms, JKS front & rear trackbars and JKS weld-on trackbar bracket reinforcements. I have an unlimted, but it gave me about 2.5" in the rear and 3.5" in the front. I have stock bumpers and no additional gear, except for a full size 35" spare tire on the tailgate.

I think if you were to put heavy bumpers, your 2-door would yield about the same amount of lift. I would probably add to your list a set of rear upper control arms since you have a shorter rear driveshaft and you'll want to correct your rear driveline angle. Also, if you have an automatic transmission, you may need to trim/grind the skidplate down so it doesn't shred your driveshaft boot. I have a manual, so I didn't have that issue.

The most important part of lifting your Jeep is not just to read posts and memorize the parts you need to buy, but to truly understand the suspension components, how they interact with each other, how they affect your Jeep and whether or not your Jeep will need specific components depending on how you drive and wheel your Jeep.

Good luck.
