Metrix Premium Chassis Parts 4 PC Front Lower Control Arm Kit

In this review of the Metrix Premium Chassis Parts 4 PC Front Lower Control Arm Kit, the bottom line is practical: this kit is for owners of compatible BMW models who need a complete front lower control arm replacement that aims to match or exceed factory standards. The reviewer finds it attractive for DIY mechanics and independent shops because it delivers a full set of four control arms with ball joint assemblies and hardware, backed by a 3-year / 36,000-mile warranty and European manufacturing certifications. The most persuasive reason to buy is the combination of fit coverage for many E8x/E9x and X1 models and the stated quality controls that go beyond OEM standards.

Key Features

• Complete kit: Includes four lower forward and rearward control arms with ball joint assemblies and necessary hardware for a front suspension refresh without chasing parts.
• Broad compatibility: Covers numerous models including 323i, 328i, 335i, 335d and X1 RWD years specified, reducing risk of ordering the wrong component.
• Manufacturing standards: Designed and produced under IATF 16949 and ISO 9001 processes, which supports consistent quality and traceability.
• Corrosion protection: Cataphoresis plating helps resist salt, dirt and water exposure, extending life in wet or salted-road climates.
• Serviceable details: High-grade steel construction and some grease fittings allow for routine maintenance and potentially longer joint life.

Who It's For

This kit suits BMW owners and independent mechanics who want a single, matched set of front lower control arms for model years listed in the compatibility guide, and who prefer parts made to higher manufacturing standards. It is especially useful when both forward and rearward arms need replacement at the same time to restore alignment and steering feel.

Customers who require OEM-branded parts or who need a single replacement arm instead of a full kit should look elsewhere. Also, those uncomfortable with suspension work should consider professional installation because correct alignment and torque are essential.

Pros & Cons

Pros

• Comprehensive four-piece kit makes front suspension jobs cleaner and quicker.
• Meets higher manufacturing standards and includes a 3-year / 36,000-mile warranty for peace of mind.
• Enhanced corrosion resistance and serviceable grease fittings improve longevity in corrosive environments.

Cons

• Some customers reported mixed assembly quality, including at least one instance of a ball joint not being assembled correctly, so pre-install inspection is recommended.

Specifications

Our Verdict

The Metrix Premium 4 PC front lower control arm kit is a strong value for BMW owners who need a full matched replacement set and appreciate parts manufactured to elevated standards. It reduces parts hunting, offers corrosion protection and a reassuring warranty, though buyers should inspect assemblies before installation because isolated assembly quality issues have been reported. For DIYers and shops seeking a complete front suspension refresh, this kit is a sensible, cost-effective choice.
