OE-Style Steering Protection

Delphi applies OE-level dimensional and material analysis to its aftermarket steering parts to support proper compatibility with the original steering system. The TBR4116 bellows helps protect the rack and pinion assembly from road contamination while maintaining the flexibility needed for steering movement. Delphi tests steering components across extreme temperatures below -40 degrees C and above 120 degrees C, and exposes parts to 720 hours of salt spray to evaluate durability in harsh conditions. This part cross-references Mevotech Supreme MK9362 for the same application.

Installation Notes

Verify the position before installation, since this part is used in both center and front applications depending on vehicle fitment. Inspect the steering rack, tie rod ends, and surrounding seals before replacing the bellows so the new boot is not installed over worn components. Mounting hardware is not included.

Quality Assurance

Delphi uses OE-focused engineering and environmental testing for its steering portfolio, including temperature cycling and salt-spray exposure, to support consistent aftermarket replacement performance.
