Delphi TD4659W Coil Spring Insulator OE Replacement

The Delphi TD4659W is a direct-fit OE replacement coil spring insulator engineered to meet or exceed original equipment standards. Constructed from durable rubber, this insulator sits between the coil spring and the spring seat, protecting both components from direct metal-to-metal contact, reducing road noise, and keeping dust and debris out of the suspension assembly.

Key Features:

• Direct-fit OE replacement — matches original equipment dimensions and material specifications
• High-quality rubber construction absorbs vibration and dampens noise transfer into the cabin
• Protects the coil spring and spring seat from wear and impact damage
• Helps exclude dust and contaminants from the suspension contact points
• Tested to withstand extreme temperatures from below -40°C to over 120°C
• Subjected to 720 hours of salt spray testing for corrosion resistance
• Validated through 250,000 duty cycles covering braking force, cornering force, and suspension travel
• Sold individually

Delphi's extensive dimensional and material analysis program ensures precise fitment compatibility between the aftermarket part and the original OE component. As a Tier 1 OE supplier to major global automakers, Delphi brings factory-level engineering and quality control to every replacement part.
