Understanding the Importance of Hub Caps

When I first started using semi trailers, I quickly realized that hub caps play a crucial role in protecting the wheel bearings and maintaining the integrity of the wheel assembly. They prevent dirt, debris, and moisture from entering the hub, which can lead to costly repairs and downtime. Choosing the right hub cap is essential for the longevity of my trailer.
