COVID-19 Update

LS Catalog

Engine Pro distribution centers stay open as essential businesses.

The Department of Homeland Security has identified "Automotive repair and maintenance facilities" and "Employees who repair and maintain vehicles, aircraft... etc. as essential to the welfare of our country." Therefore, Engine Pro distribution centers will remain "Open For Business" in the midst of major disruptions due to COVID-19. There may be some shortages and slowdowns from some of our suppliers but we are working to boost inventories to meet current and future demand.

Ordering online or by phone is preferred. Please call your distribution center to determine if any special procedures are in place for in-person sales.

While automotive supply and repair facilities may be essential to the country, you are even more essential to your family and friends! Please adhere to the guidelines outlined by the Federal, State and local authorities, use common sense and stay safe.
