  1. Fully adjustable, easy, and here on time - Posted by: Matt (8/26/15)

    I ordered this kit through ups ground and thought that the chances were very low that it would be shipped to me quickly in Vegas. I was wrong. All the boxes and parts were delivered at my door the next day. The install was very easy for the most part and the fact that everything is fully adjustable for only a 1000 bucks, I personally think this is a great deal. I'm very satisfied

  2. Excellent product ! Unbeatable price! - Posted by: Patriot (3/20/15)

    As one of the other reviews stated RC has got a few negative reviews in some of the forums and I was concerned but after some research and a good gut feeling I went with this lift on my 03 TJ. First of all it looked awesome with 33's the stance was BAD A$$ . I got more like 5 1/2 inches of lift probably from the old springs sagging . RC recommends a max of 33's with this lift but it will easily work with 35's. I used the t-case drop for now and after some adjustments and part settling virtually all vibrations are gone. As funds permit I will probably do a sye and cv shaft. As far as performance the ride on road is unbelievable. I don't know what people are talking about when they review as rough on the road. The road ride is better than NEW stock suspension. It handles great in the corners and it's just good!
    The shocks suck up washboard nicely and in the rocks everything flex's as good or better than rigs with 3 times the cost of suspensions such as a certain T flex, and Rubi express which my buddies rock. Needless to say they are not talkin much smack anymore because their wallets are a whole lot lighter and didn't get any additional benefit . Lastly,
    I got this kit with the plan to upgrade to the long arm but at this point I don't think I'll need it.
    I highly recommend this kit

  3. What most will need - Posted by: James (8/16/14)

    I bought this lift for a recently purchased 2003 Rubicon. I had previously spent a lot on building a 2006 LJ and didn't really want to go to the same expense since I never really took it to the extreme. I do get off road and wanted a capable rig, but at a more reasonable price point, the RC lift fit the bill. The good is that I got a seemingly well built lift for a very reasonable price. Having said that, there were a couple of things I found bothersome, but manageable. Threads on both bolts and nuts could really be cleaned better. On 2 of the control arms, the inside threads for the set screws were so bad, I broke 2 allen wrenches trying to get them set. I don't have the right size tap to clean the threads, so had to suffer, there were other examples as well. One of the upper front control arms wasn't sized properly to accept the lock tab of the stock hardware, so had to grind a slot and paint. Speaking of stock hardware, the kit asks that you retain your stock hardware and reuse in several areas. I would like to see all new as my hardware was rusted and required several trips to the hardware store to get replacements that should have come with the kit to deal with this. I would also like to have the joints on the control arms already assembled, but for the price I don't mind doing it myself. My stock springs were completely collapsed, so this is a great improvement. I couldn't comment on it being rough as others have said because it is so much better than what I had. I haven't gotten it out yet, but I believe the flex will suit my needs and the build quality will last for the time I have it. I think for most of the Jeepers out there, this lift will be as much as they'll ever need. Only extreme rock crawlers will need to go with other more expensive kits. I realize RC gets a bad rap on most forums, but I really appreciate the quality and amount of product you get for the cost. I will recommend their stuff.

  4. Great Lift! - Posted by: Jacob (1/10/14)

    I love this lift! Its perfect for my 04 TJ. It does ride rough but you get used to it after a while. Defiantly worth it!
