Welcome – a bit about us

Welcome to Prothero Professional Solutions. Born in June of 2015 in the back office of Truck Parts Sales Inc., Prothero Professional Solutions has grown to be more than just something on the side. Armed with the ability and the knowledge, we set out to fill a void in the heavy duty industry. We build custom and pre-built solutions for the heavy duty industry. We can build you a wiring harness for your tail light box. We can 3D print you a custom bushing if needed. We also have a library of custom parts we've built for other people that are so popular, they have become regular selling items.

Feel free to check out our catalog of items we currently build. If you don't see something you are looking for, please either call us or fill out the contact form and we will get back to you as soon as possible.

If you are looking for a custom wiring harness, please check out the electrical area where you can pick from some of our preset harnesses. In the near future, you will be able to build your own harness and we will ship it to you fully built and ready to install.

Thank you for visiting and have a great day!

Meet the people that engineer the solutions!
