Product Details

The Dorman 540-903 is a direct-fit replacement coil spring insulator designed to restore proper suspension performance and reduce noise, vibration, and harshness (NVH) in the suspension system. Coil spring insulators—also called coil spring cushions or spring isolators—sit between the coil spring and the spring seat, preventing metal-to-metal contact and absorbing road impact.

Key Features:

  • Direct OE replacement for a precise, no-modification fit
  • Manufactured from durable, high-grade rubber compound to withstand heat, moisture, and road debris
  • Helps reduce suspension noise, clunking, and vibration caused by worn or deteriorated insulators
  • Restores correct spring positioning and ride height
  • Meets or exceeds original equipment specifications

Dorman is a trusted leader in OE-quality replacement parts, engineering the 540-903 to deliver reliable, long-lasting performance. This insulator is an ideal solution when the original insulator has cracked, collapsed, or deteriorated over time.
