Detailed Description

Delphi TC8502 is engineered for the rear left upper suspension location and is listed for 2021-2024 Kia Seltos and 2018-2023 Hyundai Kona applications. This control arm uses steel construction, a bent shape, and bonded rubber bushings to match the original suspension layout and restore proper rear suspension geometry. Delphi applies dimensional and material analysis to help ensure OE-to-aftermarket compatibility, and its steering and suspension components are tested across extreme temperature and salt-spray exposure conditions.

This part cross-references Suspensia X18LA0400 for the same application. If you are searching for a rear left upper control arm for Hyundai Kona or Kia Seltos, Delphi TC8502 is the direct replacement to compare against OE specifications.

What It Helps Address

• Rear suspension looseness or instability
