Dorman 540-900 Coil Spring Insulator - Rear Upper

Dorman 540-900 Coil Spring Insulator - Rear Upper

Dorman 540-900 Coil Spring Insulator

Dorman 540-900 is a specific-fit coil spring insulator for the rear upper suspension position on select Ford and Lincoln SUVs. Built from rubber/elastomer material, it helps isolate the coil spring from the mounting surface and supports quieter, more controlled suspension operation.

Key Features

  • Precision-engineered replacement for the original equipment insulator
  • Rubber construction with a round shape for suspension isolation
  • Press-on attachment type for the rear upper spring location
  • Black finish
  • Specific fit for select Ford Expedition and Lincoln Navigator applications
  • Part number: 540-900

Detailed Description

This coil spring insulator is made for the rear upper suspension position on 1997-2002 Ford Expedition and 1998-2002 Lincoln Navigator models. Dorman 540-900 is built to match the original equipment application on these vehicles, helping maintain proper spring seating and reducing direct contact between suspension components. This part cross-references Ford F75Z5536AA and K160064 for the same application.

What It Helps Address

  • Noise from worn or hardened spring isolators
  • Metal-to-metal contact at the coil spring seat
  • Improper spring cushioning at the rear upper mount
  • Suspension vibration transmitted through the spring perch
  • Degraded ride quality caused by damaged rubber isolators

Installation Notes and Tips

Compatible With 1997-2002 Ford Expedition, rear upper, and 1998-2002 Lincoln Navigator, rear upper. Verify the spring seat and mounting surface are clean and free of damage before installation. Because this is a press-on style insulator, proper alignment during assembly is important for correct seating. Confirm the part number 540-900 matches the vehicle’s rear upper suspension configuration before service.

Quality Assurance

Dorman states that this coil spring insulator is precision-engineered and rigorously tested to provide reliable replacement performance for the original equipment on specific vehicles.
