I have put a 2" front level on my 04 Silverado 2WD. I bought new tires about a year ago 255/70/16 and noticed that when I went over a series of bumps I would get a clunking noise up front. Yesterday I put on new 2009 Tahoe wheels with 265/70/17 tires and the noise has gotten worse. I still have the stock shock on the truck and am wondering if I need to get longer ones because of the level and bigger tires. Would the shocks being to short make this happen? Thanks!
