Product Details

The Dorman 527-177 is a direct-fit rear upper rearward lateral arm designed for the driver side position. This control arm is a critical suspension component that connects the rear knuckle to the vehicle frame, maintaining proper rear wheel alignment and handling characteristics.

Key Features:

  • Direct replacement for worn or damaged OE lateral arms
  • Engineered to restore factory ride quality and handling performance
  • Precision-manufactured to meet original equipment specifications
  • Driver side (left) rear upper rearward position
  • Compatible with select Buick and Cadillac models

This lateral arm helps control rear suspension geometry during acceleration, braking, and cornering. Replacing worn lateral arms restores proper alignment angles and eliminates excessive play that can cause uneven tire wear, poor handling, and clunking noises from the rear suspension.
