Every mile on the road brings wear and tear. Here are the five parts truckers and shops replace most often: Headlights – Cracked lenses, dimming, and corrosion make these a frequent fix. Mirrors – Vibrations and minor accidents often damage side mirrors. Bumpers – Especially vulnerable in tight spaces or loading docks. Brake Lights & Turn Signals – Crucial for road safety and DOT compliance. Air Suspension Components – Leaks and sagging impact ride and load safety.
