* Engine size and type: A 2.2L four-cylinder will have a significantly lower top speed than a 4.3L V6.
* Transmission: Automatic vs. manual will have a slight impact.
* Axle ratio: Lower numerical ratios (e.g., 3.08) allow for higher top speeds, while higher ratios (e.g., 3.73) are geared for better acceleration.
* Aerodynamics: Minor modifications or added accessories can change airflow.
* Vehicle condition: A well-maintained truck will likely perform closer to its potential than one that is neglected.
Keep in mind that exceeding the manufacturer's recommended speed is dangerous and can negatively impact vehicle performance and safety.
