Keep grit, road spray, and moisture out of your steering rack with the Delphi Rack and Pinion Bellows Kit (TBR5121). The bellows is the pleated boot that seals the front rack-and-pinion assembly at the tie-rod end, holding lubricant in and contaminants out so the rack stays protected as the steering moves. This kit drops in as a front-steering replacement for the 2013-2022 Acura ILX, 2015-2020 Acura TLX, 2013-2017 Honda Accord, 2009-2013 Mazda 6, and more — see the "Vehicles it fits" section for the full list of applications.
- Built to OE standards: Delphi applies its OE steering expertise to the aftermarket, with dimensional and material analysis for close OE-to-aftermarket compatibility.
- Tested to the extreme: validated below -40°C and above 120°C and exposed to 720 hours of salt spray.
- Engineered for durability: made for consistent service life and to help reduce noise.
- Complete job: includes the necessary accessories to install the bellows.
Signs the original bellows may need replacing include a cracked, torn, or collapsed boot, grease weeping at the tie-rod end, or grit reaching the rack. If a split bellows is behind those symptoms, this kit replaces it.
