Detailed Description

Delphi TC4248 is engineered as a front lower ball joint for GM light trucks and vans, including Chevrolet Express 1500, Express 2500, Express 3500, GMC Savana 1500, Savana 2500, and Savana 3500, plus Chevrolet C1500, C2500, C3500, Tahoe, C1500 Suburban, C2500 Suburban, and GMC C1500, C2500, C3500, C1500 Suburban, C2500 Suburban, and Yukon. Delphi applies OE-level dimensional and material analysis to support proper part matching, while the joint is tested across extreme temperature and salt-spray exposure conditions to verify durability in demanding service environments. Part number TC4248 is a direct-fit style replacement for the listed front lower position applications.

This part cross-references MOOG Chassis Products K6445 for the same application.
