Product Details and Specifications

The Dorman 521-545 suspension control arm is designed to replace the original equipment part on Mitsubishi Lancer vehicles. Its steel construction combined with casting and forging processes ensures the control arm withstands the stresses of daily driving. The black coated finish helps resist rust and corrosion, extending the service life of the component. This control arm comes with a rubber bushing pre-installed, which helps absorb road vibrations and reduce noise. The welded ball joint mounting type with a threaded stud allows for secure attachment of the ball joint (sold separately). The overall length of 262.5 mm matches the OEM specifications for proper suspension geometry.

Common Applications and Problem Solving

  • Replaces worn or damaged suspension control arms on Mitsubishi Lancer models
  • Addresses issues such as excessive suspension noise or vibration
  • Corrects poor handling caused by loose or deteriorated bushings
  • Restores proper wheel alignment and suspension travel
  • Helps eliminate uneven tire wear related to faulty control arms

Installation Notes and Tips

Installation of the Dorman 521-545 control arm requires basic suspension knowledge and tools. Since the ball joint is not included, ensure you have the correct ball joint for your Mitsubishi Lancer before beginning installation. The control arm features a press-in end and bushing linkage end, so proper pressing tools may be necessary to remove and install bushings if replacement is needed. Verify torque specifications for mounting bolts and ball joint studs to maintain suspension safety and performance.

Quality Assurance and Warranty

Dorman suspension components are manufactured to meet or exceed OEM standards for fit, form, and function. The 521-545 control arm undergoes rigorous quality checks to ensure durability and reliability. While specific warranty details are not provided, Dorman typically offers limited warranties on their suspension parts to cover defects in materials and workmanship.
