  • Self centering integrated dust boots protect piston rods and seals from stone chips and road debris
  • Rising rate Elastomer bumpstops increase spring rate under extreme conditions to avoid the need for a stiff ride in day to day usage
  • High tensile steel springs offer more travel than standard steel
  • 5 year limited warranty backed by the world’s largest coilover manufacturer
