Beck/Arnley Rack and Pinion Bellows Kit P/N:103-3139
Keep road grime, water, and grit out of your steering rack with the Beck/Arnley Rack and Pinion Bellows Kit (P/N 103-3057), a direct-fit replacement for the right-hand side of a wide range of Mercedes-Benz cars. It installs on applications including the 2012-2015 C250, 2008-2015 C350, 2008-2015 C63 AMG, 2007-2011 CLS550, 2007-2016 E350, 2015-2018 E400, 2017-2020 SLC300, and 2012-2016 SLK350 — see the Buyer's Guide tab for the full list of covered models and engines.
The bellows (boot) seals the inner tie rod and rack end against contamination; when it tears or cracks, moisture and debris can reach the rack, so a fresh boot helps protect the steering gear.
Beck/Arnley parts are engineered as direct replacements for Original Equipment applications across foreign nameplates, with attention to form, fit, and function.
