Delphi TC6468 Suspension Coil Spring Seat - Rear

Rear Suspension Coil Spring Seat for OE Fit

Delphi TC6468 is a rear suspension coil spring seat made from rubber and finished in black for standard replacement service. It is built for vehicles that need a precise OE-style spring seat interface, including Chevrolet Uplander, Pontiac Montana, Buick Terraza, and Saturn Relay rear suspension applications.

Delphi applies OE-level dimensional and material analysis to help maintain proper compatibility between the original part and the aftermarket replacement. Delphi TC6468 is also tested for temperature extremes and salt-spray exposure to support durability in demanding underbody conditions.

Detailed Description

Delphi TC6468 is a rear coil spring seat engineered for OE-style replacement where the spring seat must maintain correct fit and support in the suspension assembly. The rubber material helps match the original design intent, while the measured inside and outside diameters support accurate placement in the rear suspension. This part number is a direct service option for vehicles including 2005-2009 Chevrolet Uplander, 1999-2009 Pontiac Montana, 2005-2007 Buick Terraza, 2005-2007 Saturn Relay, 2001-2005 Pontiac Aztek, 1997-2004 Oldsmobile Silhouette, 2003 Buick Rendezvous, and 1997-1999 Pontiac Trans Sport.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application. Delphi TC6468 is a practical choice when replacing a worn rear spring seat on GM platforms that rely on a rubber isolator-style component to maintain suspension alignment and noise control.

What This Part Helps Address

• Rear suspension noise caused by a worn or deteriorated spring seat
• Improper spring support from cracked or compressed rubber
• Metal-to-metal contact in the rear coil spring area
• Loss of correct spring seating on select Chevrolet, Pontiac, Buick, Saturn, and Oldsmobile models
• Fitment issues during rear suspension repair on OE-style assemblies

Installation Notes and Tips

Verify rear position and confirm the spring seat dimensions before installation. Inspect the surrounding suspension components, including the coil spring and adjacent isolators, for wear or damage before reassembly. For best results, compare the removed part to Delphi TC6468 and confirm application by year, make, model, and rear position.

Quality Assurance

Delphi uses OE-focused testing and analysis for aftermarket steering and suspension components. This part is evaluated for extreme temperature exposure and salt-spray resistance to support long-term service in harsh underbody environments.
