  • Kit includes: Two Viking Crusader shocks with AT pro-touring valving, two Hyperco springs and thrust bearing kit for easy height adjustments.
  • Street friendly performance 850 lb/in spring rate.
  • Viking Crusader double adjustable shocks.
  • Vikings front coilover kit pairs perfectly with UMIs 3057 a-arm and provides awesome performance at a great price point. Road race and auto-x cars can have increased rate and grip with an 850 lb/in spring paired with Viking Crusader AT valving. This Crusader high rebound rate shock is adjustable and easily goes from road race and auto-x use to a comfortable street ride. By increasing the rebound force, we can eliminate pitch and roll while making the car stay flat during transitions. The compression damping has a wide range and can be dialed in from comfortable cruise to race settings. The 3058-850 bolts into the stock upper mount location and does require trimming of the spring location fingers.
