Cushion the rear coil spring and quiet suspension noise with the Delphi Coil Spring Insulator TD4664W. This rear coil spring insulator seats between the coil spring and the spring seat, and it drops in as a dependable replacement for the factory insulator on many vehicles, including the 2000-2012 Chevrolet Tahoe and 2000-2012 GMC Yukon. See the Buyer's Guide tab for the full list of applications.

  • Protects spring & seat: helps shield the coil spring and spring seat from damage.
  • Quieter ride: helps reduce noise where the spring meets the seat.
  • Keeps dust out: helps block dust from the spring seat.
  • OE-focused testing: Delphi tests to the extreme — parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray, with extensive dimensional and material analysis for the best OE-to-aftermarket compatibility.

Delphi applies its OE expertise to this aftermarket insulator. If a worn, cracked, or missing insulator is behind squeaks or ride noise from the rear suspension, replacing it helps restore proper cushioning between the spring and its seat. Cataloged for rear, rear upper, and rear lower applications — check the Buyer's Guide tab to confirm your vehicle.
