• OE-validated durability: tested to the extreme, withstanding temperatures below -40°C and over 120°C plus 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.
• Inspected materials: undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
• Robot-welded: uses robot welding for consistent performance and quality.
• Precision ball studs: ball studs machined to micron tolerances for durability and smooth joint operation, with anti-corrosion protection applied for corrosion prevention and enhanced aesthetics.

The control arm locates the suspension and connects the knuckle to the chassis through its integrated ball joint, allowing controlled wheel movement while maintaining alignment. Worn bushings or a loose ball joint can show up as clunking, imprecise steering, or uneven tire wear; if a failed arm is the cause, this replaces it. Sold individually.
