The biggest reason to buy is its combination of pre-greased moving parts and aluminium construction, which delivers smoother suspension movement and less frequent service than many aftermarket alternatives. Fit reports from customers note straightforward installation and reliable function, and the part's OE interchange numbers make it easy to verify compatibility before purchase.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide vehicle compatibility:\u003c\/strong\u003e The arm fits a long list of Audi and Volkswagen models and model years, reducing the chance of ordering the wrong part for common A6, A8, S4 and Passat applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-greased joints:\u003c\/strong\u003e Pre-greased construction provides immediate, smooth movement and helps extend service intervals compared with ungreased replacements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminium construction:\u003c\/strong\u003e The lightweight aluminium body resists corrosion while maintaining strength for stable suspension control under normal driving loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOE interchangeability:\u003c\/strong\u003e Carries OE\/interchange numbers such as RK80556 and 4B3407151A for straightforward cross-referencing with dealer parts lists.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing standards:\u003c\/strong\u003e Produced to exceed OEM standards with IATF 16949 and ISO 9001 certifications, supporting consistent build quality and dimensional accuracy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty backed:\u003c\/strong\u003e A 3 year \/ 36,000 mile limited warranty offers added confidence in reliability after installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis control arm is aimed at competent DIY mechanics and independent shops replacing worn suspension components on compatible Audi and Volkswagen models, including various A6, A8, S4, S8 and Passat years listed by the manufacturer.
