What will be the difference beetween a Combo Kit and a Suspension Kit

Yes, back in the fall PJF had that 3-4" kit for the JK's going for around $500. You'd have to talk to PJF 4x4 to see what today's pricing would be.

Thanks for the reply Twinkie ...

I just call them , 500$ + tax for a 3.5" lift kit or 1000$ installation + tax included... no too sure if I should try to install it myself.... or I take the little PDF from Rough Country.

Having just gone through this process, I can offer a few additional things to thing about.

1. Anything more than a 2.5" lift will require new driveshafts, as a minimum.
2. Think hard about 'extension' brackets. These are typically a weak-point. You would be better off with replacement track bars, sway links, control arms, etc.
3. Drop brackets are okay up to about 2", otherwise get longer brake lines. You will thank me when you fully articulate and still have brakes.
4. Extend the breather tubes for your diffs. Simple brake lining will do.
5. Match the springs and shocks. Much better ride.
6. Make sure get longer control arms, or at least relocation brackets (see note 2) to retain correct camber. Better highway driving.

I had my lift done by Malmberg. AEV 2.5 JKU http://www.aev-conversions.com/shop/shop-by-category/suspension/jk-dualsport-xt-suspension-2-5.html
Charged me 4 hours. Great job.

Good luck.

Personally i would take the manufaturers suggestion as just that... I have seen 4"+ kits saying they recommend a sye and drive shaft but had no issues when installed without and have also seen trucks (i.e mine lol) with only a 2" bb lift kit that shouldnt need any modification to driveline....but it does....so best bet is to ask people running the exact setup you plan to run. Although realizing thats not always an option places like national 4wd are very helpful with these kinda questions but remeber they will obviously reccomend whatever the manufaturer recomended. Sorry if this doesnt help just figured id end the debate over what lift is the max you can run without issues

Another route (that I used) was to ask jeep build shops that have installed the product you are considering. In my case, I developed a relationship with Fortec 4X4 in Atlanta, including visiting them in March. Although at first glance they seem to compete with Quadratec, the owners at Fortec do not sell what they themselves have not installed. Put another way, they only sell what they would put in their own jeeps. They build ~50 jeeps a month for Atlanta and Miami Jeep dealers. They helped me alot in deciding which kit to go with.

I also agree with 91redxj - take manufacturer's recommendations with a grain of salt. They're in the business to sell you their kit. Do your own research.

X3 what said above. Keep in mind what size tire you want to run as that should be the first question that was asked. JKs can fit 35's with a 2" lift since they are naturally highlined. TJs need the extra 2"s on top of that unless highlined or running metalcloak fenders which do the same thing. Also keep in mind if you are going bigger tires you may have to look at regearing your diffs which will increase the cost dramatically.

There are several JK and Wrangler specific forums that will provide you with more info than you will ever need:

Info from a jk website.
Q: Are new driveshafts needed after installing a lift?
A: You really should consider installing a new rear double cardin U-joint style drive shaft if you have lifted your Jeep JK Wrangler 3" or more and have a 2-door. This is needed because the short rear drive shaft of the 2-doors will be at a steep enough angle that the CV boots will wear out prematurely. However, in order to do this, you will need to buy a set of rear adjustable upper control arms so that you can properly set your pinion angle. 4-Door Unlimited models do not have this problem as their rear drive shafts are very long and a lift will not effect the angle of it too much. As far as the front goes, if you have an automatic transmission, you will need to replace the drive shaft with a double cardin U-joint style unit as well as the diameter of aftermarket shafts will be considerably narrower and will not come into contact with the transmission and/or skid plate. Failure to do this will result in the tearing of the factory drive shaft boot as it makes contact with the transmission. Manual transmissions will not have this problem and keeping the factory front drive shaft will not be a problem.

NOTE: On a 2012-Up, you will want to install a new front drive shaft regardless if you have an automatic or manual transmission. Assuming you install new, longer shocks with your lift, the extra droop you will see at a flex will cause the slip shaft boot on the drive shaft to tear. However, that is just one problem you will encounter. Even if you install exhaust spacers or relocate the cross over, the CV boot at the output shaft will be sitting at a significant state of pinch and this will cause it to fail prematurely.

I just ordered a Rough Country kit despite many negative reviews. I ordered direct from manufacturere, but in restrospect jfp4x4 was cheaper. I also found that the shock were pretty much poking out of the shipping box. Nothing looks damaged, but I can let you know when the kit goes in hopefully this week. I figure that I'll get a cheap 3" lift for now then go all out with a 6" lift and 33+" tires in a year or two.
