Delphi TBR4479 is a rack and pinion bellows for steering systems on select Hyundai and Kia vehicles. It is built using Delphi OE-focused dimensional and material analysis to support proper fit and reliable steering protection in demanding conditions.

Key Features

• Rack and pinion bellows for steering gear protection
• OE-based engineering for aftermarket steering applications
• Tested for temperature extremes below -40°C and above 120°C
• Exposed to 720 hours of salt spray during validation
• Fits select 2015-2018 Hyundai and Kia models
