Common Replacement Reasons

• Hood, hatch, or panel no longer stays open securely
• Slow or weak lift action from a fatigued gas spring
• Uneven support or reduced holding force
• Original strut shows wear at the socket ends or rod seal

Installation Notes

Match the compressed length, extended length, force rating, and socket-style connections before installation. Confirm the vehicle is one of the listed Mazda MX-5 or Mazda MX-5 Miata applications and verify the non-power-retractable hardtop requirement where noted. Inspect mounting points for wear or damage before snapping the plastic socket ends into place.
