  1. I put it on my 2015 - Posted by: Kevante (3/4/15)

    I installed this kit on my brand new(under 1000 miles) on my 2015 2Dr sport. Install took a while but was pretty straight forward. The springs are so much softer than other big name kits I have used. The kits is complete and bought the RC drive shafts and fuel skid also which make all the difference. I have enjoyed the ride quality so far and has some great road manners. Sonny people have poked at the RC name and I was hesitant at first, so far what a great decision. The sway bar discos are ok at best is my only area of concern. When ordering the kit the exhaust loop was back ordered so I just make my own exhaust and put in 2.5 straight pipe with a Glasspack.
    Great flex and the 2.2 shocks so far are Amazing... Again kit is very nice!!!!

  2. After installing a 4" in long arm kit I found it's not a drive way job. - Posted by: Kenneth (3/10/14)

    Installed a 4"long arm kit on 2013 Rubicon. I found this to be of very good quality. It's a complete kit well packaged with good instructions. Thanks Rough Country you have a winner here.
