Hi, I tried to look here for new Bilstein shocks but can't find the right size in the forum. My existing shocks break mine and my G/F's back over the smallest bumps. It's a stock 2006 Lvl II. Less the original Bilsteins. I see the 4600's are ok but can't discern which ones to get for their length. Can someone please steer me in the right path to buying something that isn't bone jarring but fit? Lol?
