We just finished installing the Black Diamond 3 1/2" lift on my buddies YJ. He was upgrading from the stock suspension. During the upgrade, we decided not to connect front or rear trackbars, but he is still using his swaybar up front. According to him, the ride is vastly improved. (A little bouncy, but his springs haven't settled yet either)
We took it offroad to flex it out a little & it did okay - granted, he left his swaybar connected up front so it's not going to have mad flex like that.
Overall, he is very pleased with the kit. It came with, and we installed the black diamond shocks.
'01 TJ with mods... :)
