Keep road grime, water, and debris out of the steering gear with the Beck/Arnley Rack and Pinion Bellows Kit (P/N 103-3167). This bellows (boot) covers the tie-rod end of the rack and pinion, sealing the assembly against contamination so the internal components and grease stay protected. It installs on the RIGHT-side position and is designed as a direct replacement for the Original Equipment application, matching OE form, fit, and function. It fits a wide range of Audi models, including the 2020-2025 A6 Allroad, 2019-2025 A6 Quattro, 2019-2025 A7 Sportback, 2017-2025 Q5, 2017-2025 Q7, 2019-2025 Q8, and 2018-2025 SQ5 — see the Buyer's Guide tab for the full list of 27 applications and engine details.
- One-piece neoprene boot: a single-piece design (this is not a split boot).
- Complete for installation: includes the boot and two clamps.
- Quality construction: built for durability.
- Application specific: engineered for this vehicle to match OE form, fit, and function.
A torn or cracked steering rack boot lets moisture and dirt reach the rack and pinion, which can lead to premature wear — replacing a failed bellows helps restore that protective seal.
