What does the term "frame straightening" refer to in collision repair?

The term "frame straightening" specifically refers to the process of restoring a vehicle's frame to its original dimensions after it has been damaged, typically as a result of a collision. When a vehicle experiences an impact, the frame can become bent or twisted, which can compromise its structural integrity and affect alignment and safety. Frame straightening involves using specialized equipment, such as hydraulic jacks and frame racks, to pull and realign the frame back to its factory specifications.

This is crucial for ensuring that the vehicle handles properly and maintains safety standards, particularly in the event of future collisions. By restoring the frame to its original shape, technicians can effectively repair the vehicle and help restore its performance and safety features.

The other options focus on different aspects of frame handling; for instance, strengthening the frame or replacing components are important steps but do not define frame straightening specifically. Modifying the frame for performance improvements also diverges from the intent of frame straightening, which is solely about restoration rather than enhancement.
