I think thats an awesome idea! I'm looking at the 6" long arm Rock Krawler lift for my 00 TJ. Less lateral forces means a smoother ride then the short are I have on it now, better clearance, and much more durability

I plan on the 3.5" LA Rock Krawler with TNT Customs Hyline series f/r w/4.5" flare for a LCG build this winter/spring on an LJ. I would definitely go down in BL height. I would even go to stock and do a flare kit. That is of course if you don't plan on any larger tires in your future.

Rock Krawler builds tough stuff with great quality. They have stood behind their product at every turn for my customers.

Namaste,

Allen

Looks like a clone of the Rough Country lift. I like Rock Krawlers higher end long arm kits, but I wouldn't consider buying that lift. If you're going to go short arms look into Currie, Savvy, or Rokmen. That's my $.02

I pulled the trigger this past winter on the 3.5" LA kit. I love it, the only regret is that I didn't do it sooner! WTF was I thinking? Highway Ride is great and trail performance is absolutely amazing! Read the full review here: http://www.wranglerforum.com/f5/tj-l...s-25145-3.html

Rock Krawler's products and customer service are top notch. They're right in my back yard so I can stop down to their shop and pick up the parts I need, and the guys who work there have helped me adjust and dial in my lift/steering that I got from them after hours, instead of just booking out and going home. I've seen their products stand up to severe use and abuse from myself and those in my club, but some of the hardest users are the guys who work in their shop; and it still comes out with flying colors, and always gets you home. Great company, excellent products, all made in the USA. when I talked to Jeremy (the owner) he mentioned that they manufacture everything in their shop here in NY's capital district, and the stuff they don't manufacture he tries to stay with suppliers of USA made goods, which is an added bonus IMO. If you've gotta pay for it, why not support our economy, right?


I even got the invite to go on a ride with them, that's how I got my Jeep into Jp Mag

The only suggestion I have is go for the long arm kit. Same amount of lift, more flex, and the better road handling and ride quality alone is totally worth the price. Upgrade to their updated xfactor steering when it comes out in the spring of '12 (I think), and you'll be set. Solid set up.

Exactly what I think. Rk makes a great long arm kit. I wouldn't run the short arm kit the OP posted about though.

6" long arm = better clearance than 4" short arm. The front and rear bumpers, and trans/transfer case skid plate are raised up by 2" over the 4" short arm kit. The RK long arm kit increases the belly skid upwards by 2" over stock, and the frame side control arm attachment points are tucked up nice and neatly compared to other long arm kits. The RK long arm kit is one of the best pre made kits for a Jeep TJ.

Short arms are fine, but the arms in the link you posted run JJ style ends on one side of the arm, and Rubber/polly bushings at the other end. I don't like the Rubber/Polly bushings being paired with JJ style ends. The JJ style ends will flex nice and neatly, but that will transfer more tourque/twisting force into the Polly bushings since they don't flex equally, thus causing them to experience twice as much loading since they're the limiting factor in the control arm...

The longer arms still hang down lower than ANY short arm, and thats if you stick with those humongous LCA mounts on the frame. And plus 6" of lift is just ridiculous, not needed on ANY rig.

Not saying its not a nice kit, and dont know how they are. But facts are short arms provide more clearance on the arms, especially with 6" degree angles compared to 4" short arms, and that 6" of lift is unneccesary. You can gain the tummy height, and breakover and departure and approach angles with other means.

I agree, go with dual JJ arms if you can Jake.

I could argue with you about this all day, but it wouldn't help the OP.

Yes, if you can. I dont know if rock crawler sells any arms that do, if not itd be awesome to find some aftermarket. Youll prolly be ok with the poly sides, but the JJ's are primo.

If you're going to run any type of spherical rod end, (Heim joint) or spherical cartridge joint, (Johnny Joint or clone) then run the same at both ends.

If you run a more flexible joint on one end of the arm, then the twisting force as the arm moves will end up being totally controlled/limited by the less flexible joint/end, thus causing twice as much wear and tear on the limiting bushing/joint... So the extra flexy joint on the one end will be limited to half as much as it could achieve, and the non flexy side will wear out twice as fast.

I can agree to that The RK long arm kit actually has more ground clearance at the frame underbelly between the axles than the factory set up does with short arms though, plus the lower control arms are slightly bent and solid stock to keep them up and out of the way, while keeping factory clearances. The RK long arm kit includes a tummy tuck and doesn't hang the lower control arm frame side mounting brackets below the frame any more than the stock trans case skid plate does, it's actually tucked up a bit higher than stock. I don't run it myself, but I know a few guys that do and it's a very nice system.

I couldn't afford the entire kit for my Jeep all in one shot, so I've been buying it a few pieces at a time. I started first with the entire front end, Currie JJ axle housing kit, and Currie upper and lower control arms, then I followed that up with Currie 4" lift springs on all 4 corners and Currie Bump stops all the way around. My next step will be Currie rear lower control arms, and either Currie or Rokmen upper control arms... it's a bit more expensive than getting an entire kit all at once, but it fits my budget to be able to buy the parts I want as I save the money to get them.

Good luck with your build If you only replace the lower control arms like the picture in your post shows, then please replace your factory bushins in the remaining factory parts at the same time so that you don't end up posting a DW thread shortly after you upgrade your other parts.

I'm anal about things, I keep seeing posts that start out with "I just got new such and such, and now I have DW"... the whole suspension is supposed to work together as a system, and replacing a few parts with higher quality parts will leave the remaining parts to deal with higher stress levels than they were designed to handle. You wouldn't replace the brake caliper, rotor, and pads on one side without doing the other side would you? Why would you upgrade only one side of the control arm? Or only the bottoms and not the uppers? I've never heard anyone say " I replaced my upper and lower control arms and bushings, my track bar and bushings, and now I have DW!" It's always someone that only did something half way...
