Monroe RideRefine SDD (stroke dependent damping) add-on valve provides highly refined, luxury-level ride characteristics. SDD technology dramatically enhances comfort by improving plushness and road isolation, enabling manufacturers to tune vehicles for greater everyday comfort with minimal impact on handling.

  • 1 Main-valve bypass directs oila into SDD valve, providing separate, tunable damping of small strokes for reduced vibration and harshness.
  • 2 Following completion of small piston stroke, damper's main valve resumes normal operation.
