I could not find Trailbalzer parts on the energy suspension website. I have a 02 trailblazer 4wd. Can you tell me where you ordered from?I just bought a front and rear end-link set from energy suspension they have poly urethane bushings and so on, i got 2 end links, 2 swaybar bushings, and a bar that goes through the bushings for 24.95 EA for each kit and i got a front and a rear kit. And they come with installation directions for your car specifically so that's a bonus!!
