Metrix Premium Front Left Lower Forward Control Arm - Durable Fit

In this review the Metrix Premium Front Left Lower Forward Control Arm is evaluated for owners of 2007-2013 BMW X5 and 2008-2014 BMW X6 who need a direct-fit replacement. The bottom line: this control arm delivers a reliable, OE-interchange fit with pre-greased components that simplify installation and reduce initial maintenance. Its European manufacturing and IATF 16949/ISO 9001 credentials make it an appealing option for anyone replacing a worn suspension arm and wanting a part that aims to exceed OEM standards and arrive ready to install.

Key Features

• Vehicle compatibility: Directly replaces the front left lower forward control arm on 2007-2013 BMW X5 and 2008-2014 BMW X6 for a correct fit without modification.
• Pre-greased joint and bushing: Pre-greased components reduce initial break-in noise and make the assembly move smoothly from first installation.
• Steel construction: Solid steel material provides durable resistance to road stresses for long-term chassis stability.
• OE interchange numbers: Matches common OE/interchange references RK620798, CMS101143, CB14353, and 31126773949 so it is easy to verify compatibility.
• Quality certifications: Manufactured under IATF 16949 and ISO 9001 standards, indicating controlled production and traceable quality processes.
• Warranty coverage: Backed by a 3 year / 36,000 mile limited warranty from installation date for added ownership confidence.

Who It's For

This part is best for DIY mechanics and independent shops working on BMW X5 (2007-2013) or X6 (2008-2014) chassis repairs who want a direct replacement that meets or exceeds OEM design. The pre-greased ball joint and bushing are particularly helpful for installers who prefer fewer immediate service steps after fitting.

Those who should look elsewhere include owners of other model years or different BMW models, or technicians who require an exact OEM-branded part for brand-specific warranty reasons. If a full OEM provenance certification is mandatory for a particular repair program, confirm acceptance before purchase.

Pros & Cons

Pros

• Good fit for specified X5 and X6 years based on OE interchange numbers customers use to verify compatibility.
• Pre-greased assembly simplifies installation and reduces early wear or noise complaints.
• Manufactured in Europe with IATF 16949 and ISO 9001 certifications, suggesting consistent quality control.
• Three year / 36,000 mile limited warranty provides practical protection after installation.

Cons

• Only supplied as a single arm; buyers replacing both sides must purchase two units separately.
• May not satisfy buyers seeking original factory-branded parts despite exceeding OEM standards.
