Detailed Description

Delphi TC1846 is engineered for the front lower suspension position and built to match OE dimensional and material requirements. Delphi applies extensive dimensional and material analysis to help ensure proper fitment and consistent performance, while its testing program exposes parts to extreme temperatures and prolonged salt spray for durability validation. This ball joint is a direct-fit style replacement for vehicles such as the Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 3500 HD, and Hummer H2 in the listed model years. This part cross-references MOOG Chassis Products K6693 and Mevotech Supreme MK6693 for the same application. Delphi TC1846 is a practical choice when servicing worn front suspension joints on Chevrolet Silverado and GMC Sierra HD platforms.
