Even though custom shock valving is no problem for the crew at Walker Evans, they've still got several formulas figured out. John Searle of Walker Evans Racing showed us a drawer-full of pre-packaged pistons and valve stacks. John also explained the service department's modus operandi: "We don't nickle and dime people who send in their shocks. If someone is already paying for a rebuild and they want their valving changed, there's no charge for doing that because we've already got their shock apart. We encourage people to send their shocks in to us, rather than working on them themselves. Our phone number, (888) WEE-RACE, is right on our sticker, and we really do want people to call us when they've got a question."
