Rock Krawler stock mod vs flex system vs...?

I'd like to apologize in advance if this has been asked before, but I was unable to find any information on this topic.
After months of research, I've decided on a Rock Krawler suspension system for a 2.5" lift. Now, I've heard that these can give additional height based on the weight of the vehicle- especially with two doors, which I have.
My plan was to go with a Stock Mod system with Teraflex shock extensions, and then buy other components as I could afford them. After further reading, I've come to find that the Stock Mod system tends to require extended brake lines to help deal with the additional height. Fine. So I begin looking at the Flex system, which includes extended brake lines, as well as front LCAs. These are supposedly especially recommended for two door models.
(Questions about the Rock Krawler Stock Mod - JeepForum.com)
The more I read, however, the more seems to be "highly recommended" for the lift. If the 2.5" lift is going to potentially give me 3" of lift or more, then will I run in to more issues with drive shafts and other additional components along the way? What exactly is the minimum that I can get away with for a while without running into any issues? Should I be considering another lift that gives closer to the advertised hight?
Thank you for any help or input.

It really depends on what you want the lift for. Are you wheeling it, and if so how hard? If you are just looking for height there are tons of options out there to give you lift that won't create other potential issues. What is your main goal and then better recommendations can be offered.

I'd like a lift that gives a decent height, yet is capable off road. I'm not doing anything that's too intense right now, but something that gives a bit more performance than a budget boost would be nice. I live in southern North Carolina currently, so most of my wheeling will be on dirt trails or in mud for a while with my ultimate goal being a trip to Uwharrie. Sorry, I should have included this information in my original post.

I'm running RK coils on my 2 door. Lifted pretty high with no weight. Just be prepared for it and any issues.

No need to be sorry just want to keep you pointed in the right direction. With companies like Rock Krawler and Metal Cloak be advised that advertised height is with a fully armored rig. Bumpers, winch, skids, corners, etc. without that you will get more lift than you think. A 2.5" kit like you are talking about will net 3-3.5" likely if you are mainly stock. Get exhaust spacers to gain clearance for the driveshaft and you should be pretty set for a while. Also be aware that over 3" of lift can cause the death wobbles without adjustable control arms to correct geometry due to the lift height. Doesn't always happen but possible. Not trying to scare you but trying to make you aware of potential items that can pop up.

I appreciate the advice. I have a good bit of armor already, so hopefully that will keep weight down.

I'm running a RK 2.5 max travel with ace bumpers, rails and a winch. I think I'm sitting at 3 to 3 1/4" of lift. I wheel and have no issues with the drive shift after 10K miles.

Just keep in mind that all of the RK systems are upgradeable and use the same parts. So you could start with the stock mod, see if you like it. If not, you can add the parts to make it the same as the flex.

Just look at the parts list. All of the 2.5" lifts have the same parts to start with, you just get more parts with a more expensive lift.

You do get what you pay for. If you get a more expensive RK lift, your rig will ride better on and off road.
