I need new shocks. Actually, I've needed them for a while, but the budget just wouldn't let me. Anyway, I'm trying to do a little future planning for the Blazer, and the Rancho RSX shocks seem to be a good idea. Anyone using these? How's the ride? Would RS9000's be a better choice? Or the Edelbrock IAS? Most of my driving is (unfortunately) street and highway, so that's my primary concern. Thanks! Semper Maintenance!
