Built for front sway bar service on select Buick Lucerne and Cadillac DTS applications, this Delphi TD4788W bushing kit is a direct-fit option for restoring stabilizer bar support and suspension control. Delphi applies OE-level dimensional and material analysis to help ensure proper fit and consistent replacement performance.

Product Details

Delphi TD4788W is engineered for front stabilizer bar service where OE-style rubber bushings are required. The part is validated through temperature exposure below -40 degrees C and above 120 degrees C, along with extended salt-spray testing, to support durability in demanding undercar conditions. This makes it a practical replacement for worn sway bar bushings on 2008-2011 Buick Lucerne and 2006-2011 Cadillac DTS, front, including Cadillac DTS models with Heavy Duty Suspension.

This part cross-references MOOG Chassis Products K201316 and Mevotech Supreme MK201316 for the same application.

What It Helps Fix

• Front-end clunking or rattling from worn stabilizer bar bushings
• Excess sway bar movement caused by deteriorated rubber
• Loose or imprecise front suspension feel
• Noise during turns, bumps, or uneven road surfaces
• Fitment issues when replacing an OE-style front sway bar bushing

Installation Notes

Verify the stabilizer bar diameter and bushing dimensions before installation. This front bushing kit does not include grease fittings or mounting hardware, so reuse or source any required related components separately. Confirm vehicle application by year, make, model, and suspension configuration before ordering, especially for Cadillac DTS models with Heavy Duty Suspension.

Quality Assurance

Delphi uses OE-focused dimensional and material analysis to support proper aftermarket fitment. The part is tested for extreme temperature exposure and salt-spray resistance to help maintain performance in real-world suspension service.
