Metrix Premium Front Left Lower Rearward Control Arm - Durable Fit

In this review of the Metrix Premium Chassis Parts front left lower rearward control arm, the bottom line is simple: this replacement is for BMW owners who need a robust, OE-interchange quality part that installs without fuss. The reviewer found it especially suited to owners of 2018-2021 BMW 530e, 2017-2021 530i xDrive, and 2017-2021 540i xDrive models who want a direct-fit replacement with factory-beating standards. The control arm is pre-greased and made from aluminium, which delivers smooth movement and a longer service life compared with a basic aftermarket arm.

Key Features

• Compatibility: Direct fit for specified 2018-2021 530e and 2017-2021 530i xDrive and 540i xDrive models, making replacement straightforward for these BMWs.
• Pre-greased bushings: Ships pre-lubricated to reduce initial wear and provide smoother suspension action immediately after installation.
• Aluminium construction: Lightweight corrosion-resistant material helps maintain suspension geometry while reducing unsprung mass.
• OE interchange: Matches OE/interchange part numbers 31106861181 and CMS101587 for simple cross-referencing during purchase or service.
• Manufacturing standards: Made to exceed OEM standards with IATF 16949 and ISO 9001 certification, supporting consistent part quality.
• Warranty: Backed by a 3 Year / 36,000 miles limited warranty from installation for added peace of mind.

Who It's For

This control arm is aimed at DIY mechanics and professional technicians replacing a failed or worn left lower rearward control arm on compatible BMW 530e, 530i xDrive and 540i xDrive models. It is also a good option for owners who prefer parts meeting certified quality standards and want a pre-greased unit to save time during installation.

Those who should look elsewhere include drivers with BMWs outside the listed model years or non-xDrive variants, and anyone seeking a multi-part suspension kit rather than a single control arm replacement.

• Fits the listed BMW models precisely, reducing installation time and alignment headaches.
