Detailed Product Overview

Delphi TD4121W is engineered as an OE-style suspension stabilizer bar bushing kit for front-end sway bar service. Delphi applies dimensional and material analysis to help ensure proper OE and aftermarket part compatibility, and the brand subjects its steering and suspension components to extreme temperature and salt-spray testing. This part cross-references MOOG Chassis Products K80076 for the same application.

Common Repair Uses

Installation Notes and Quality Assurance

Confirm the sway bar diameter and front position before ordering, since this kit is specified for 35mm diameter front bars. Delphi’s OE-focused testing includes exposure to temperatures below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray, to validate material durability for aftermarket use.
