Metrix Premium Front Lower Forward Control Arm with Ball Joint

Our review of the Metrix Premium front lower forward control arm finds it best suited for owners of late model Audi and Volkswagen sedans who want a direct-fit, long-lasting replacement. 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.

Key Features

• Wide vehicle compatibility: 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.
• Pre-greased joints: Pre-greased construction provides immediate, smooth movement and helps extend service intervals compared with ungreased replacements.
• Aluminium construction: The lightweight aluminium body resists corrosion while maintaining strength for stable suspension control under normal driving loads.
• OE interchangeability: Carries OE/interchange numbers such as RK80556 and 4B3407151A for straightforward cross-referencing with dealer parts lists.
• Manufacturing standards: Produced to exceed OEM standards with IATF 16949 and ISO 9001 certifications, supporting consistent build quality and dimensional accuracy.
• Warranty backed: A 3 year / 36,000 mile limited warranty offers added confidence in reliability after installation.

Who It's For

This 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. It works well for owners who value a part that arrives pre-greased and ready to install, saving time during a suspension job.

Those driving vehicles outside the stated compatibility list, or needing a performance-tuned aftermarket arm for track use, should look elsewhere. Buyers who require a steel rather than aluminium arm for heavy-duty off road use should also consider alternative parts designed specifically for those demands.

Pros & Cons

Pros

• Direct-fit compatibility for many Audi and Volkswagen models makes verification quick and installation straightforward.
• Pre-greased ball joint and bushing reduce initial break-in and lower immediate maintenance needs.
• Aluminium material offers corrosion resistance while keeping unsprung weight down, aiding ride quality.
• Backed by a 3 year / 36,000 mile limited warranty for added peace of mind.

Cons

• Aluminium construction, while lightweight and corrosion resistant, may not suit extreme-duty or track-focused applications where sturdier steel components are preferred.
• Compatibility depends on VIN and specific wheel configurations for some years, so buyers must double-check fitment before ordering.

Specifications

Our Verdict
