8. Our AlterKtion kit came with Viking Warrior double-adjustable coilover shocks. These lightweight twin-tube aluminum dampers have independent control of compression and rebound with 19 positions for each (361 combinations total). Each Warrior shock is dyno tested and serialized with a two-year warranty. Besides quality, performance, and adjustment range, RMS also likes Viking products for their larger 1.25-inch spherical bearings, which do not require special spacers and an extra assembly step. Viking Warrior springs are guaranteed to remain within 2 percent of their original free height over their lifetime and are silver powdercoated for great looks.
