Those go in place of the stock rear bump stops but you need to do the free travel mod first. There’s plenty of info on that here and on the web.Maybe y'all can answer one question for me. The shop that installed my lowering kit didn't install the two energy suspension bumpstops that came with Tony's kit. Where exactly do they go? Because my steering needs some TLC, it looks like I'm getting sway bars, GMT900 brakes, and new wheels and tires and I want to make damn sure my suspension is exactly perfect this time around.
