Fitment and Key Features

This Delphi rack and pinion bellows is made for Mercedes-Benz steering systems that require a left-side bellows profile. Delphi subjects steering components to extreme temperature cycling and extended salt-spray exposure to verify material durability and dimensional stability. Part number TBR4453 is also referenced for the same application under Beck/Arnley 103-3116.

• Delphi part number TBR4453
• Compatible with Mercedes-Benz C300, C350, E350, CL550, CLS550, CLS63 AMG, GLK250, and GLK350 applications listed above
• OE-focused fitment analysis for steering system compatibility
• Built for exposure to harsh temperature and corrosion conditions

What This Bellows Helps Address

• Damaged or cracked steering rack bellows
• Contamination entering the steering rack area
• Loss of protection around the rack and pinion assembly
• Wear-related steering boot replacement on Mercedes-Benz vehicles

Installation Notes

Verify the steering side before ordering, since this listing includes left-side fitment for select CLS applications and N/A-position fitment for other listed models. Confirm the vehicle year, model, and steering configuration against the application data before installation. Delphi TBR4453 should be matched to the original bellows shape and dimensions for proper sealing and steering rack coverage.

Quality Assurance

Delphi applies OE engineering standards to its aftermarket steering portfolio and validates parts through temperature and corrosion testing. The brand’s dimensional and material analysis is used to support consistent fitment and performance across the listed Mercedes-Benz applications.
