Detailed Description

This Delphi suspension coil spring seat is engineered for OE-style fit and material compatibility in the front suspension. Delphi applies dimensional and material analysis to help ensure the replacement seat matches the original application, while its rubber construction supports the coil spring and helps maintain proper seating in the suspension assembly. Delphi TC6545 is listed for front lower use on 1995-2001 Toyota Camry, 1995-2001 Lexus ES300, 1995-2003 Toyota Avalon, 1998-2003 Toyota Sienna, and 1999-2003 Toyota Solara, plus front upper use on 2003-2017 Chevrolet Express 2500.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Noise from a worn or deteriorated spring seat
• Improper coil spring positioning in the front suspension
• Vibration transfer through aged rubber components
• Suspension clunking caused by damaged seat material
• Uneven spring support from a compressed or cracked seat

Installation Notes and Tips

Verify whether your vehicle uses the front upper or front lower position before ordering. For fitment, confirm the application against the vehicle’s suspension layout, since Delphi TC6545 is position-specific by model. On Toyota Camry, Toyota Sienna, Toyota Avalon, Toyota Solara, and Lexus ES300 applications, this part is listed for the front lower position; on Chevrolet Express 2500, it is listed for the front upper position.

Quality Assurance

Delphi subjects its OE-focused suspension and steering components to temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. That testing, combined with dimensional and material analysis, supports consistent OE-style performance and fit for Delphi TC6545.
