Used this kit along with the 4-link rear and trac-bar kit when I went to one-tons on my TJ. Simply set up the fram brackets and everything fits easily from there! No guessing or complicated computer caluculators. The frame brackets slide over and weld on easily and are beyond heavy duty in their construction. I have wheeled this kit for years without a single issue. The best part of this kit is the customer service and support you get when you buy from TMR. The guys are always ready and willing to go the extra mile to help you out if you need it!
