This bellows kit is tested for demanding temperature extremes and salt-spray exposure, helping it meet the expectations of steering system service where protection of the rack and inner components matters.

What It Helps Address

  • Cracked or torn steering rack bellows
  • Contamination entering the rack and pinion assembly
  • Loss of protection around steering components
  • Wear-related replacement during steering service
  • Front steering boot service on select BMW applications

Installation Notes and Tips

Verify the bellows dimensions against the original part before installation, especially the end diameters and overall length. Confirm front-position application and inspect the steering rack, tie rod ends, and clamps for wear before reassembly. Because mounting hardware is not included, reuse or source the required hardware separately as needed. Fitment includes 2006 BMW 325i front, 2006 BMW 330i front, 2007-2014 BMW 335i front, 2009-2011 BMW 335d front, and 2012-2014 BMW X1 front, with thermoplastic version notes where listed.

Quality Assurance

Delphi uses OE-focused testing and material validation for its steering components, including exposure to extreme temperatures and extended salt-spray testing. That engineering approach supports consistent aftermarket replacement performance for Delphi TBR4223.
