Product Details

The Dorman 521-288 is a front passenger side upper suspension control arm and ball joint assembly engineered as a direct-fit replacement for select Mercedes-Benz vehicles. Constructed from lightweight aluminum, this assembly restores proper suspension geometry, steering precision, and ride quality without requiring modification or fabrication.

Key Features:

  • Direct OE Replacement: Designed to match the original equipment assembly for a precise, bolt-on fit
  • Complete Assembly: Comes with the ball joint and bushings pre-installed, reducing labor time and simplifying the repair
  • Aluminum Construction: Lightweight yet durable aluminum build matches OE material specifications
  • Corrosion-Resistant Finish: Protective coatings help guard against rust and corrosion for long-lasting performance
  • Rigorously Tested: Undergoes industry-leading evaluation to ensure smooth ride quality, directional stability, and predictable handling dynamics
  • Sold Individually: Includes one (1) passenger side front upper control arm assembly

Dorman's OE Solutions line is engineered by examining original equipment failures and improving upon them, giving repair professionals and vehicle owners a reliable, cost-effective alternative to dealer-only parts.
