  • Precision Tolerances: Computer-controlled grinding for exact 3.00 in. ID, 12.00 in. free height, and 200 lb/in rate to match coilover components perfectly.
  • Silver Powder Coat: Durable corrosion-resistant finish protects against road salt, moisture, and maintains spring performance over time.
