Detailed Description

Delphi applies OE engineering knowledge to its aftermarket steering portfolio, and TA3550 reflects that approach with dimensional and material analysis focused on fit and function. This front outer tie rod end uses a steel tie rod body, POM bearing material, and a rubber dust boot to support consistent steering response in demanding temperature and corrosion conditions. It is a straight, non-adjustable replacement part with left-hand and right-hand thread directions at the ends, and it is listed for front outer placement on Lexus RX350, Lexus RX350L, Lexus RX450h, and Lexus RX450hL models.
