Seal out the grit and moisture that destroy your steering gear with the Beck/Arnley Rack and Pinion Bellows Kit 103-3121, a direct-fit steering rack boot kit for the 2013 Infiniti JX35, 2014-2020 Infiniti QX60, 2013-2025 Nissan Altima, 2016-2023 Nissan Maxima, 2015-2024 Nissan Murano, and 2013-2020 Nissan Pathfinder. See the "Vehicles it fits" section for engine-level fitment. The bellows flexes with the inner tie rod as the rack strokes, keeping the grease in and contaminants away from the rack, inner tie rod, and seals.
- One-piece neoprene boot: this is not a split boot.
- Complete installation: includes the boot and two clamps.
- Matches OE form, fit and function for a direct replacement on foreign nameplate applications.
- Application specific with quality construction for durability.
A cracked, torn, or leaking bellows lets dirt and water reach the rack — signs this boot may need replacing. If a failed boot is behind grease slinging or contamination, this kit replaces it. Have an alignment performed after service.
