  1. Rough Country Long Arm kit for WJ - Posted by: Jim (12/16/13)

    I installed this kit early in 2013, and have been driving on and off road since.
    Install is straight forward, and instructions are excellent.
    I have two basic complaints on the kit:
    The flag nuts are a royal pain. Long nosed pliers and safety wire are your friends!
    The one piece control arm and trans mounts force you to remove suspension when you need to drop the trans for work. I actually modified this with another crossmember and it is prefect now.
    Great kit over all, plenty of adjustment if you want to go taller (I am using 6.5 in springs now)
    The new style flex joints work well, and are very similar to other better known brands.

    I would and have recommended this kit to others, and wouldn't hesitate to buy it again.
    This is the second kit I have installed on my personal vehicles.
