Truck modifications refer to the various changes and upgrades made to a truck to enhance its performance, appearance, or functionality. Common modifications include installing a lift kit to increase ground clearance, adding aftermarket wheels for improved aesthetics, or upgrading the exhaust system for better engine performance. These modifications can also involve practical enhancements, such as adding a towing package for increased hauling capacity or installing a bed liner to protect the truck bed. Many truck owners customize their vehicles to suit their specific needs, whether for work, recreation, or personal style.
