Product Details

Delphi TD4803W is engineered as a suspension stabilizer bar bushing kit for the rear-to-frame location. Delphi applies OE-level dimensional and material analysis to aftermarket steering and suspension parts, helping maintain proper fit on the intended Cadillac CTS and Cadillac STS applications. This part cross-references MOOG Chassis Products K201379 for the same application.

Compatible With 2008-2014 Cadillac CTS, rear to frame, and 2010-2011 Cadillac STS, rear. It also fits 2005-2009 Cadillac STS, rear to frame, with 17mm diameter sway bar. Use Delphi TD4803W when replacing worn rear stabilizer bar bushings on these Cadillac models.

Common Problems It Can Address

• Clunking or rattling from the rear suspension
• Excess sway bar movement at the frame mount
• Worn, cracked, or flattened rubber bushings
• Loose-feeling rear suspension response
• Noise caused by deteriorated stabilizer bar support

Installation Notes

Verify sway bar diameter and rear-to-frame mounting location before installation. Clean the mounting surface and inspect the stabilizer bar for wear or corrosion before fitting the new bushings. Because mounting hardware is not included, reuse or replace related fasteners as needed during service. Confirm the application by matching the vehicle year, model, and rear suspension configuration to the listed fitment.

Quality Assurance

Delphi tests suspension and steering components across extreme temperature ranges and salt-spray exposure to support OE-style durability. The TD4803W is a standard replacement part built for consistent fit and material performance in the intended Cadillac CTS and Cadillac STS applications.
