- Spring protection: Helps shield the spring and spring seat from damage.
- Noise reduction: Helps reduce noise at the front upper spring position.
- Dust control: Helps keep dust out.
- Tested to the extreme: Delphi tests its parts to withstand temperatures below -40°C and above 120°C, along with 720 hours of salt spray exposure.
- OE compatibility: Delphi's extensive dimensional and material analysis is aimed at the closest possible match between the OE part and the aftermarket part.
Signs a coil spring insulator may need replacing include squeaking or creaking from the spring area over bumps, or an insulator that is cracked, worn thin or missing. When replacing it, inspect the spring and spring seat as well.
