Small steps Daniel-son. LOL

today was vac pump relocation day. Had relocated to under the hood when I installed my winch but recently realized that's where my spod will go. So now it's mounted above the sway bar via the EVO kit.

Very close to pulling the trigger in a rear bumper/tire carrier for the 35s. Leaning towards the rampage. Don't know about front yet.

Man, I need a raise.

KrawlOff-Road.com LOL thanks guys! I try to do what I can when I can. I think sometimes that my fingers are going to catch fire!

Now, to be honest, I am not running the stock front DS on our 2dr but it is NOT because of the 2.5" RK lift. We did it to test the prototype of our new KrawlOff-Road line of drive shafts. Like I said, we do a lot of the RK 2.5's and you will be fine...

I know the angle is worse on the 2 door, but my expirience is that you will be fine.
Jason is either a damnable temptress or, in the words of Chef: "He's a succubus chidren."

I'm getting more comfortable w/ the idea of going w/ the RK, just need to do some more reading to put my mind at ease. Still need to get my aftermarket bumpers first, which will help to alleviate some of my concerns regarding the achieved lift height.

Glad you're enjoying it.

If I go w/ RK, and that's still an "if" at this point, I'll certainly start w/ the 2.5 flex and go from there.

I've been reading a few other threads and I've tradieda few msgs w/ Jason. My biggest concern at this point is that I've read the 2.5, when installed on a 2-door, adds more than 2.5....closer to 3 or 3.5.

At this time, I'm trying to stay away from the inherent "issues" of a taller lift that would require things like full adjustablitiy, alteration of pinion angle, new drive shaft, etc.

I don't want to overcomplicate things right out of the gate. I just want to run 35s with no rub and go from there.

Feel free to educate/correct me on my statements.

Jason's last few comments aligned w/ what I was already thinking.....start w/ the 2.5 flex system and build from there.

Very interested that you found the stock gearing to be adequate. I'm a lead foot like you and I tend to drive my Jeep like i'm still in a sports car. When I do upgrade, I'll give the stock gears a shot, but I'll make sure to hae some funds set aside to regear, just in case.

Great thread, write-up, review.

I definately need to stay off here if I'm drinking in the near future else I'll end up placing an order /w RK.

Torfer Looks great! I was thinking of getting the 2.5 max lift, but after reading this I might step up to the X-factor. Moving the rear axle back scares me a little bit though.
Originally I wanted a 3.5" lift, but after talking with people about having to replace the drive shafts and other problems that come with going over 2.5" I figured I would save the hassle and money. Is this going to be a problem with this lift?
I know everyone recommends wheels with a 4.5 BS, was wondering if a 4.75 BS would work with this kit. I am also looking at the Rancho rs9000xls, any comments of these shocks with this lift? I assume I will also need to buy bump stops with this, is that the only extra purchase I will need?

It felt a little odd being higher up, and the the larger tires make the whole truck feel bigger. Now I wouldnt change a thing.

The 4.10 gears are just fine with the 34.4" Duratracs, The gearing feels almost better. I didnt like cruising at 80mph before with my tach needle out of the green zone. About 2800-2900 rpm with the stock wheels and 4.10 gears, now Im under 2500 RPM at 80 MPH and although there isnt much pick up in 6th gear now, that is what I wanted from the beginning.

The best car I owned before my jeep was a 2001 corvette. I totally had a love affair with it, and its 6th gear was not for accellerating, it was a cruising gear.

What I mean is, if you want to get good highway mileage, lower RPM in 6th gear is the way to get it. So you crank through the gears to get up to speed and then drop it in 6th to cruise at 75 or 80. Its a more comfortable vs. the way it was before with me pressing harder on gas to cruise at the speed I wanted.

I have a set of 4.88s in the garage but Im not going to change the gearing, That would put me over 3100 RPM at 80 MPH. When you have to drive 3 hours to rausch creek to wheel it, You want to be able to cruise at a higher speed.

I haven't taken it wheeling, but I will this weekend and Ill let you know how the 4.10s hold up in the rocks.

Side note- Im running the tires at 38psi and I like it better than the lower PSI (29psi) that it left rock krawler with. If you feel like your ride is squishy, make your tires a little harder with higher PSI.

I am looking to do the exact same build with my 2012 rubi, the RK kit with the almost 35" duratracs. Thanks for the post.

PieFace We broke the Axle cam on that trip.

I had just climbed through the most incredible black section at rausch creek. Pulled the camera out, and I could see mud under the lens.

I still have the file, but its corrupted.

Also, when you tape something when your off road, it always looks CRAZY when your driving through it, Then you see the tape later and it may as well have been a driveway. Video completely tames the terrain.

Thanks Matador.
Not a problem brother, you did a great job doing the the interviews. It came off natural and your follow up questions were on-point. I really liked the parts break-down and the explanation of the seals and your follow up questions, they were exactly what I was thinking. The rest of the stuff is minor and could be worked out through editing. The basis for the video, your interviews and unique shots are there. Now, its just a matter of pulling it all together.

In regards to the music, I understand the need to use royalty-free stuff but there are much better options available and I would limit its use anyway. The intro could be a quick couple of seconds and you should get right into it. Again, I would use your unique under-body and full articulation shots as your off-roading examples. They are different and interesting. But, I would keep the bulk of the videos informational and your interviews. I understand the need to keep them loose and unscripted but I would run down the general topic with the person your interviewing first, then start recording.

Overall you had some good shots to work with like the under-body angles or the full articulation shots that should have been used more often. The "inclinometer" inlet shot was useless due to the camera shaking, I probably would have left that out and would have opted with simple type overlay.

Overall its a great first crack at video production, I think if your "Ross Allen" you have the basics for a good interviewer. Your clear and articulate when you speak and you can tell that some of your questions are scripted but your follow ups are just as strong.

Videos finally!!

Hey Everyone,

Here they are as promised. They took a little longer than expected. Here's the first one, it us talking to Justin Z from Rock Krawler.

Justin worked on the install for us, but before the parts went into the truck we made him explain them. Tell me what you think.

Sway bar disconnected

Hope this helps. I also made sure to position it inboard far enough so as not to be any kind of problem while flexing and turning
Thats genius! I had little straps on mine and they both tore off. One of them while i was turning. I herd a loud "snap" and then a really loud "ping". I almost shat myself but i was way to puckered for anything to come out! Thought i broke something expensive. Ended up my disco slapped my spring pretty hard. No damage.

I know I'll need to trim my Rubi rails and pinch seem. I'm not worried about doing that. I just didn't want my rear 35s to look goofy and uncentered.

Would that switch work or would I also need the adjustable rear track bar too? Or would stock work for now? And would the front UCAs be okay stock for now?

Yes, of course the RK arms is better and the ends are nicer but once you get to this point, most people will not see much of a differance from going from the Max Travel to the X-Factor. Now, I am not saying you can't go that route and upgrade from the Max Travel to the X-Factor because you can. RK has all their kits where you can change and grow the kit as you see fit.

Also, you can run the stock rear track bar with this kit. There again is it as nice as the RK one? No but you still can us the track bar. I would not really worry to much about it unless you start to go higher than the 2.5" or there is a issue with the stocker.
