Metrix Premium Front Left Lower Control Arm with Ball Joint

In this review the Metrix Premium Front Left Lower Control Arm with Ball Joint is evaluated for owners of full-size GM trucks and SUVs seeking a durable, ready-to-install replacement. The bottom line: this control arm stands out for its solid cast iron construction, pre-greased joint for smoother initial movement, and broad vehicle coverage, making it a practical choice for someone replacing a worn front lower arm who wants long life and straightforward fitment.

Key Features

• Broad vehicle compatibility: The unit fits many GM models from 2007 to 2016, reducing the risk of ordering the wrong part for common Silverado, Sierra, Tahoe and Yukon variants.
• Cast iron material: Cast iron construction provides strength and resistance to bending under the heavier loads of trucks and large SUVs.
• Pre-greased ball joint: The pre-greased assembly helps ensure smoother movement immediately after installation and extends initial service life.
• OEM interchange numbers: Supplied with common OE/interchange numbers such as RK620888 and 10355407, which aids verification and part matching during replacement.
• Quality standards: Manufactured to exceed OEM specifications and produced under IATF 16949 and ISO 9001 quality systems for consistent reliability.

Who It's For

This control arm is aimed at owners and independent mechanics who need a direct replacement for the front left lower control arm on a range of GM models including Cadillac Escalade, Silverado 1500, Sierra 1500, Tahoe, Suburban and Yukon years listed by the manufacturer. It is especially useful for those who prioritize a part that arrives pre-greased and built to exceed OEM tolerances.

Drivers with non-listed vehicles or those requiring a different suspension geometry, upgraded performance parts, or aluminum components should look elsewhere. For routine OEM-style replacements on the specified models, this part is a practical choice.
