Metrix Premium Front Left Lower Control Arm w Ball Joint - Fits 03-07

In this review of the Metrix Premium Front Left Lower Control Arm w Ball Joint & Bushing Assembly, the bottom line is simple: this is a direct-fit replacement for specific Mercedes-Benz C-Class AWD models that prioritizes durability and ease of installation. The reviewer found it best for owners who need a reliable OEM-replacement control arm that arrives pre-greased and backed by a clear warranty. It is not a universal part, so correct vehicle fitment is the single biggest reason to buy - if it fits your model years, it removes much of the guesswork.

Key Features

• Vehicle Compatibility: Direct compatibility with 2006-2007 C280 AWD and C350 AWD plus 2003-2005 C240 AWD and C320 AWD ensures a correct fit for those specific models.
• Pre-greased: The control arm ships pre-greased to reduce initial break-in wear and provide smoother movement from first installation.
• OE Interchange Numbers: Includes OE/interchange references like RK622163 and 2033300307 to help confirm fitment against dealer parts lists.
• Quality Standards: Manufactured to exceed OEM expectations and produced under IATF 16949 and ISO 9001 certifications for consistent build quality.
• Warranty: Comes with a 3 Year / 36,000 mile limited warranty from installation, offering tangible post-purchase protection.

Who It's For

This part is best for Mercedes-Benz owners and independent mechanics who need an exact front left lower control arm replacement for the listed AWD C-Class years and want an item that arrives pre-greased and ready to install. It suits budget-conscious restorations where reliability and documented interchange numbers matter.

It is not suited for vehicles outside the stated model years or for those seeking a universal or adjustable performance control arm. Buyers who need fully OEM-labeled original parts from a dealer or specialty performance upgrades should look elsewhere.
