Product Details

The Dorman 521-645 is a front driver side lower suspension control arm and ball joint assembly designed as a direct replacement for the original equipment on select Cadillac, Chevrolet, and GMC truck and SUV applications. This complete assembly delivers professional-grade quality at an affordable aftermarket price.

Key Features:

  • Complete assembly includes pre-installed ball joint and bushings for time-saving installation
  • Constructed from durable steel with protective coatings for long-lasting rust and corrosion resistance
  • Non-adjustable, stock-style design ensures proper fit and function
  • Underwent rigorous industry-leading testing to ensure smooth ride quality, directional stability, and predictable handling dynamics
  • Direct replacement for OEM part—installs exactly like the original equipment

Control arms are critical suspension components that work with springs and shock absorbers to absorb road impacts while maintaining proper wheel alignment and tire-to-road contact. This Dorman OE Solutions control arm meets strict quality standards and provides reliable performance for vehicles that have experienced wear from hard usage, potholes, or curb impacts. Sold individually for the front left (driver side) position.

This company is pretty good even when I found what I was looking for cheaper then some other websites

so far so good

Great prices! Fast shipping on parts that were in stock! Parts that came factory direct took a few extra days longer. But couldn't beat the prices!

fast and easy with great pricing. short bed liner and dark window vents at one stop shopping.

As expected...

Quick and easy

Easy, and parts are in stock. Fast shipping. Very satisfied.

best price available plus like the ability to pay with amazon

There was no description with my item but the part number is correct so I'm optimistic.

Good prices and also discounted shipping sold me on it.

Easy and quick. A+++
