17. All RMS AlterKtion and Street-Lynx suspensions are equipped with Viking Warrior double-adjustable shocks. These are some of the nicest dampers we’ve seen, and include a multitude of features, like dual 19-position damper adjustment for compression and rebound, lightweight construction, and ride-height adjustability. Each U.S.-built shock is tested independently on a shock dyno, serialized, and comes with a two-year warranty. Viking also warrants their springs to maintain within 2 percent of their spring rate for the life of the spring. RMS additionally states that if you need a different spring rate from the one initially supplied, they will swap them out for you at no cost.
