Detailed Description

Delphi applies OE-focused dimensional and material analysis to this trailing arm to support proper fit and suspension alignment on the rear right side. The steel, stamped construction is paired with a rubber bushing for controlled movement, while the painted finish helps protect the part in everyday service. Delphi tests components for temperature extremes and extended salt-spray exposure to evaluate durability under demanding conditions. This part number TC8301 is a direct replacement-style option for Toyota Corolla, Camry, Corolla Cross, Avalon, C-HR, Prius, Prius AWD-e, and Prius Prime rear right applications.

This part cross-references MOOG Chassis Products RK643578 for the same application.
