  1. 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.

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