This is a stylish track that should come with Jeep from the factory. The stock steering wheel is so poorly designed that it poses a major safety issue. I've been using these bars for about a week without the lift and have noticed a slight diff rubbing. I installed the alignment kit and everything is fine now. If you don't plan on lifting, get the Teraflex model, it has a lot more flex where the chain comes out of the diff case. For installation I went to Lowe's and bought 8 9/16" round head bolts. Use red Loctite and torque to 125 pounds on each side. Torque with large adjustable pliers. Now I can use the Parkway sawmill at Lower NY 684 and other freeways and don't worry about literally dying in traffic Buy it if you have a small elevator!
