I have a 4" RC lift I'm almost ready to install however, I am fumbling around with the idea of bump stops. I keep reading how necessary they are to save my shocks, tires, and fenders. The thing is, I cut my fender flares, and will not be upgrading my tires from 31s to 33s for a couple months (unless you want to donate money to me). So with my 31s, cut fender flares, and 4" lift, are bump stops still necessary? If so, how do I determine what size bump stops I need?
