Eibach ERS 18.00 in. Length x 3.00 in. ID Coil-Over Spring - 600 lb/in Rate

This Eibach ERS coil-over spring measures 18.00 inches in free length with a 3.00 inch inside diameter and 600 lb/in spring rate, designed for custom coilover strut assemblies. It suits performance vehicles in drag racing, circle track, road racing, and off-road applications requiring firm suspension control. Engineered for high-load durability, it delivers consistent response under extreme conditions.

Key Features

  • High-Tensile Chrome Silicon Steel: Provides resistance to fatigue for extended service life in racing environments.
  • Shot-Peened Construction: Increases surface strength and prevents stress cracks during repeated high-impact use.
  • Preset and Scramblized Ends: Ensures square, stable seating on perches for accurate installation and load distribution.
  • Silver Powder Coat Finish: Resists corrosion and maintains appearance in harsh track conditions.
  • Precise 600 lb/in Rate: Delivers firm damping control with 18 in length supporting up to 1,980 lbs max load and 13.81 in max travel.

Product Notes

  • Verify shock absorber stroke length matches spring travel to avoid bottoming out.
  • Inspect regularly for wear in competitive use; replace if rate changes exceed 5%.
  • Ships in protective cardboard sleeve to prevent damage.

Installation Notes

  • Professional installation recommended.
  • Requires compatible 3.00 in ID coilover perches and retainers; not for use without proper strut housing.
  • Torque hardware to manufacturer specs; use thread locker on adjuster threads.
