Metrix Premium Lower Control Arm Kit Front Left & Right - Durable Fit

In this review the Metrix Premium Chassis Parts front lower control arm kit is evaluated for drivers who need a direct replacement for worn suspension on compatible GM sedans. The kit's single biggest selling point is that it delivers a complete pair of aluminium lower control arms with preinstalled ball joints and cotter pins, allowing an installer to restore front-end stability quickly. For anyone replacing both left and right arms at once, or seeking parts that claim to exceed OEM standards and come with a 3 Year / 36,000 miles limited warranty, this kit merits close consideration.

Key Features

• Complete kit: Includes one front left and one front right lower control arm with ball joint assemblies, which simplifies a twoside repair without sourcing separate parts.
• Material: The aluminium construction reduces unsprung weight while maintaining structural strength for consistent steering feel and ride stability.
• Fitment coverage: Compatible with specific GM models including 2007-2009 Saturn Aura and 2005-2010 Pontiac G6, making it suitable for common repair needs on those platforms.
• OE standard compliance: Designed and manufactured to exceed OEM specifications and built under IATF 16949 and ISO 9001 processes, which supports long term reliability.
• Warranty backed: A 3 Year / 36,000 miles limited warranty from installation provides added confidence for buyers replacing critical suspension components.

Who It's For

The kit is best for DIY mechanics and independent shops repairing 2007-2009 Saturn Aura, 2005-2010 Pontiac G6, or compatible Chevrolet Malibu model years where aluminium arms are required. It is particularly useful when both sides need replacement, since the kit supplies left and right arms and cotter pins for a complete front suspension refresh.

Those who drive vehicles outside the listed fitment or who require OEM-branded originals for dealer warranty matching should look elsewhere. Also, owners seeking parts for models not explicitly listed should verify fitment before purchase.
