Firestone is a household name for tires, but they’ve got their hands in the suspension industry, too. Ride-Rite, a division of Firestone, manufactures air helper springs and suspension components. And, at the 2012 SEMA Show, we spoke with their Regional Sale Manager, Todd Green. He described their full replacement suspension system for haulers and towers—the R4Tech Suspension System. The kit includes air springs, lead springs and load-adaptive shocks for maximum performance and handling.
