TY I am going to start hunting for the right sway links tonight. I want to find adjustable but I think I will have to go with TF.I just bought the TERAFLEX 10.25" (for 2.5" lift) to use on the rear as I install the AEV 2.5' lift kit. The current STOCK rear links will go on the front for a perfect fit.
Dont' know about a "need", but I can tell you ppl love the ride with new, properly fitted links for a new lift. Like you said, they are pretty cheap, so as might as well match it to your new lift. Just my opinion, but I AM doing it next week. TF also has longer ones for a 3-4".
