I don't know how/what Bushwacker makes theirs of, but ours are vacuum formed. We'll find out soon enough how brittle they are though! One small snag, my damn hardware hasn't made it in yet for the flares. If that would have come in I was going to be able to throw it on the lift at work to install the flares/lift tomorrow.....looks like that'll be put off until the hardware is in. :-/ I was looking forward to getting the lift done this week so it's more driveable. Right now with the track bar being worn and rear suspension being blown it's annoying to drive. haha
