I have a 2008 Silverado with a FWC Raven Shell. It has 140,000 miles and is still on its OEM shocks/struts. I'm not interested in lifting it or upsizing tires. In fact, I just bought some new Wildpeaks, ever so slightly upsized so that I could get an E rated version. I'm thinking about just putting Bilstein 4600s on it, because at that mileage, as nice as it still is, I'm not sure a big dollar suspension upgrade makes sense. I'd like it to be a little more compliant on washboard and potholes, but still need lateral rigidity for the camper. Any other ideas or would you just replace the originals with something newer and nicer?
