Detailed Description

Delphi TC1607 is engineered as a standard replacement suspension ball joint for front lower positions on vehicles such as the Ford Mustang, Ford Thunderbird, Lincoln Town Car, and Mercury Grand Marquis. Delphi applies OE-focused dimensional and material analysis to help maintain proper fit and suspension geometry, while the greaseable design supports routine serviceability. The included dust boot helps protect the joint from contamination, and the bolt-on mounting style is designed for direct replacement use where this application is specified. This part cross-references MOOG Chassis Products K8259 for the same application.
