Product Overview

Delphi TC8015 is a rear suspension coil spring seat engineered for vehicles that need a precise rubber isolator and spring support interface. The OE-focused design approach includes dimensional and material analysis to help maintain proper compatibility with the original suspension layout on 2002-2005 Ford Explorer and 2002-2005 Mercury Mountaineer models. Delphi also subjects its parts to temperature and corrosion testing to verify performance under demanding conditions.

What It Helps Address

• Rear spring noise caused by worn or hardened rubber seating surfaces
• Loss of proper spring support at the rear suspension
• Uneven rear ride height related to deteriorated spring seat material
• Metal-to-metal contact where the original seat has cracked or compressed
• Fitment issues when replacing a damaged rear coil spring seat on Explorer or Mountaineer

Installation Notes and Tips

Verify rear suspension orientation before installation and compare the old seat to the new Delphi TC8015 for diameter and profile match. Inspect the coil spring, isolators, and surrounding suspension components for wear while the assembly is apart. Confirm application by year, make, model, and rear position before final assembly.

Quality Assurance

Delphi applies OE-based engineering and testing methods to its aftermarket steering and suspension portfolio. This part is evaluated for dimensional accuracy, material consistency, temperature resistance, and salt-spray exposure to support dependable replacement performance.
