Front Left Lower Rearward Control Arm for BMW 11-15 Models - Premium

In this review of the Front Left Lower Rearward Control Arm, the bottom line is straightforward: it is aimed at BMW owners who need a direct-fit replacement that matches or exceeds factory standards. Designed as a single-piece aluminium control arm with a pre-greased ball joint and bushing, this part stands out for long-term serviceability and construction that meets IATF 16949 and ISO 9001 requirements. Our review finds it particularly valuable for owners of 2009-2017 5 and 7 Series variants who want a reliable, warranty-backed component without the uncertainty of generic aftermarket parts.

Key Features

• Vehicle Compatibility: Fits a wide range of BMW models from 2009 to 2017, making it easy to replace the left front lower rearward control arm on many 5 and 7 Series variants.
• Pre-greased Ball Joint: Ships pre-greased to reduce initial break-in friction and extend the control arm's service life for smoother steering response.
• Aluminium Construction: The aluminium material offers a balance of strength and reduced unsprung weight, which helps preserve handling characteristics.
• OE Interchange Numbers: Cross-references include RK621992, CMS101169, 522-871, and 31126775963 so installers can confirm fitment before purchase.
• Quality Standards: Manufactured to exceed OEM standards with IATF 16949 and ISO 9001 certification for consistent build quality and reliability.
• Warranty Coverage: Backed by a 3 Year / 36,000 mile limited warranty from installation, giving purchasers added confidence.

Who It's For

This control arm is best for owners and independent mechanics repairing suspension on compatible BMW models including ActiveHybrid 7, 740i, 740Li, Alpina B7/B7L, 535i GT, 550i GT, 750i/750Li and 760Li model years listed in the fitment. It is well suited to drivers who value factory-level standards, a pre-greased joint to simplify installation, and a clear OE interchange reference for part matching.

It is not intended for custom suspension builds or applications outside the listed BMW models; anyone with severe off-road use, modified suspension geometry, or who needs a different material finish should look for a dedicated performance or OEM-specific alternative.
