Detailed Description

Delphi TC6255 is engineered as a rear right upper suspension control arm for vehicles that require precise OE-style fitment and suspension alignment. Delphi applies dimensional and material analysis to match OE and aftermarket requirements, and the part is validated for demanding temperature and corrosion exposure conditions. This part cross-references Dorman OE Solutions 520-198 for the same application.

Fits 2002-2006 Pontiac Montana, rear right upper; fits 2005-2006 Saturn Relay, rear right upper; fits 2001-2005 Pontiac Aztek, rear right upper; fits 2002-2004 Oldsmobile Silhouette, rear right upper. Delphi TC6255 is also a direct-fit reference for select Buick Rendezvous and Chevrolet Uplander rear suspension service.

What This Part Helps Address

• Rear suspension looseness or instability
• Worn control arm bushings affecting ride quality
• Improper rear wheel alignment from suspension wear
• Clunking or noise from the rear upper suspension area
• Uneven tire wear related to rear suspension geometry

Installation Notes and Tips

Confirm the rear right upper position before ordering, since this control arm is not adjustable and does not include a ball joint or grease fitting. Compare the mounting-hole spacing and overall dimensions to the removed part to verify match before installation. After replacement, perform a professional alignment to restore suspension geometry on the Buick Rendezvous, Pontiac Montana, and related applications.

Quality Assurance

Delphi uses OE-focused engineering and material testing for aftermarket steering and suspension parts. TC6255 is exposed to temperature extremes and salt-spray testing during validation to support durability in real-world service.
