Front Left Lower Rearward Control Arm w Ball Joint & Bushing - Durable

In this review of the Metrix Premium chassis control arm the bottom line is straightforward: this part targets owners of select Audi A6, A7, S6, S7 and RS7 models who need a reliable OEM-grade replacement without paying dealer prices. The reviewer found the unit's aluminum construction, pre-greased joints and clear OE interchange numbers make diagnosis and installation quicker, and the included 3 year / 36,000 mile limited warranty provides confidence for road use. If precise fit and long-term movement without extra prep matter, this control arm is built for that role.

Key Features

• Compatibility: Covers multiple Audi models from 2012-2018 so buyers can match the OE interchange numbers RK622832 and 4G0407693J to confirm fit.
• Pre-greased design: The ball joint and bushing arrive pre-lubricated to reduce initial break-in noise and improve immediate functionality after installation.
• Aluminium construction: Lightweight aluminium offers durability and corrosion resistance compared with lesser stamped steel arms, helping maintain handling geometry.
• Exceeds OEM standards: Manufactured under IATF 16949 and ISO 9001 processes, the part aims to provide consistent dimensions and finish that outperform typical aftermarket alternatives.
• Warranty backed: The 3 Year / 36,000 mile limited warranty from installation gives practical protection against early defects for most road use cases.

Who It's For

This control arm is best for independent shops, DIY mechanics and Audi owners who need a direct replacement part for front left lower rearward suspension on compatible A6, A7, S6, S7 and RS7 models. It suits people who value pre-greased components to reduce install time and who prefer parts manufactured to certified quality standards.

Those who should look elsewhere include drivers with vehicles outside the listed model years or people requiring custom performance arms; this is a replacement part designed to match OEM geometry rather than change handling characteristics.

Pros & Cons

Pros

• Fits specified Audi A6/A7/S6/S7/RS7 applications well and uses known OE interchange numbers for easy verification.
• Pre-greased ball joint and bushing make initial movement smooth and reduce immediate maintenance needs.
• Aluminium build and certified manufacturing deliver reliable durability and consistent quality.
• Comes with a 3 Year / 36,000 mile limited warranty for added peace of mind.

Cons

• Designed strictly as an OEM-style replacement, it does not offer performance tuning or altered suspension geometry.
• Quantity in the box is one arm, so buyers needing both sides must purchase separately.

Specifications
