These Schumacher Racing Products rear shock springs are a factory replacement hard-rate option for the Icon, Atom, and Eclipse platform vehicles. Finished in nickel, they are sold as a pair and are designed as a direct-fit replacement for the rear suspension. Selecting the correct spring rate is critical to dialing in handling, and this hard variant gives tuners a stiffer option for track conditions that demand reduced body roll or faster rebound.
