Key Features

• OE-focused steering component engineered for aftermarket replacement use.
• Helps protect the rack and pinion assembly from dirt, moisture, and road debris.

• Tested for extreme temperature exposure and long-duration salt spray resistance.
• Part number TBR4540 for easy identification during ordering and service.

Detailed Description

Delphi applies its OE steering expertise to this rack and pinion bellows, using dimensional and material analysis to match the original part as closely as possible. The design is intended to maintain the protective barrier around the steering rack while supporting consistent fitment across covered Hyundai and Kia platforms. This part number, TBR4540, is a practical choice for service work on Hyundai Elantra, Hyundai Kona, and Kia Niro applications where the bellows must seal out contamination and preserve steering component protection. Delphi TBR4540 is also cross-referenced to Beck/Arnley 103-3149 and 57740-F2000 for the same application.

What It Helps Address

• Torn or deteriorated steering rack bellows
• Contamination entering the steering rack area
• Moisture exposure around steering components
• Fitment issues caused by an incorrect replacement boot

Installation Notes and Tips

Verify the vehicle application against the fitment list before installation. Inspect the steering rack, tie rod ends, and surrounding components for wear or damage before replacing the bellows. Confirm that the replacement boot seats correctly and that the steering system moves freely after service.

Quality Assurance

Delphi subjects this steering component to extreme temperature testing from below -40 degrees C to above 120 degrees C, along with 720 hours of salt spray exposure. Those validation steps support OE-level performance expectations for the aftermarket steering portfolio.
