Front Left Lower Control Arm w Ball Joint & Bushing Assembly - Fits

In this review the Metrix Premium Front Left Lower Control Arm is judged for owners who need a reliable, direct-fit replacement for RAM 1500 suspension work. The bottom line: this part is aimed at DIY mechanics and shops who want a durable, pre-greased assembly that replaces OE unit RK641504 and related interchange numbers, with the main reason to buy being its combination of cast iron construction and a 3 year / 36,000 mile limited warranty for long-term confidence.

Key Features

• Direct fit compatibility: Designed to fit a wide range of RAM 1500 models from 2006 through 2023 where specified, reducing the need for modifications during installation.
• Pre-greased assembly: Arrives pre-lubricated to provide smoother movement out of the box and to extend the service life of the ball joint and bushing.
• Cast iron construction: Built from robust material to handle normal driving loads and resist premature wear under typical road conditions.
• OE interchange coverage: Cross-references common OEM numbers such as RK641504 and 55366439AG to simplify parts lookup and ordering.
• Quality management certified: Manufactured to IATF 16949 and ISO 9001 standards, indicating consistent production quality.
• Warranty backed: Includes a 3 year / 36,000 mile limited warranty from installation, offering tangible after-purchase protection.

Who It's For

This control arm is best for RAM 1500 owners and independent mechanics who need a like-for-like replacement for front left lower suspension on specified 4WD and RWD models, and who value a pre-greased, certified part that meets or exceeds OEM standards. It is also a good choice for fleet maintenance where part traceability and warranty matter.

Less suitable for drivers seeking a lightweight or performance-tuned aftermarket upgrade, since the part is cast iron and focused on durability and factory-equivalent function rather than weight savings or bespoke performance geometry.
