Laser cut with precision bending. Manufactured from 1/4" thick steel for heavy duty applications. Available for Jeep Wranglers 1976-2006 (CJ/YJ/TJ/LJ). This product is a must for anyone carrying over a 31" tire and/or using a tire carrier. Since the stock rear cross members of Jeeps are thin and not made to carry added weight, this is the best possible solution and upgrade you can do. The gas tank etc. does not need to be dropped. Some YJ/TJ Jeeps that are using aftermarket shackles etc. may have to make modifications to fit. This is a quick and easy install that anyone can do with a few wrenches. Kit includes the brackets and all needed mounting hardware. Brackets come stock in black color. Brackets use stock bolt hole locations, but offer additional mounting holes if you desire to drill into the frame for additional mounting points. Please specify year of Jeep at time of purchase so we can get you the correct brackets.
