Product Details

The Dorman 521-585 is a rear driver side upper forward suspension control arm and ball joint assembly, engineered as a direct OE-quality replacement for select BMW X5 and X6 models. Constructed from lightweight aluminum with a natural finish, this assembly restores proper suspension geometry, directional stability, and confident handling to your vehicle.

Dorman's engineering team analyzes the original equipment design to identify common failure points, then incorporates improvements to help prevent those same failures from recurring. Each assembly undergoes an industry-leading evaluation process to ensure a smooth ride, stable dynamics, and long-term durability.

Key Features:

  • Direct OE Replacement: Bolt-on fitment designed to match the original equipment specifications exactly
  • Complete Assembly: Comes with pre-installed ball joint and bushings — no separate purchases needed, reduces installation time and labor
  • Aluminum Construction: Lightweight, high-strength aluminum build matches the OEM material and weight requirements
  • Corrosion-Resistant Coating: Additional protective coatings provide long-lasting resistance to rust and corrosion
  • Rigorous Testing: Validated through industry-leading quality and safety testing for sustained, secure performance
  • Non-Adjustable / Stock Geometry: Maintains factory suspension alignment settings

Dorman part number 521-585 is sold as a single assembly (driver side). Hardware is not included. Verify fitment using your vehicle's year, make, model, and trim before purchase.

Easy description and part numbers

I am a repeat shopper and always have a pleasant experience shopping with Autoplicity.

Best price around! Will be back. Fast shipping too. On the same day I ordered from Autoplicity which is in Illinois I made an order from California---it is not here yet. Three days from Illinois, going on a week plus from California. Great job Autoplicity!!

Good so far

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Great prices will shop here again.
