The most popular form of dirt track racing across the country, Modified racing is what most people think of when you talk about dirt track racing. Modifieds have come a long ways, but originally got their name because racers were modifying as many things as possible to gain a competitive advantage. Speedway Motors has all the Modified parts and racing accessories you'll ever need on our shelves year round to keep you prepared for whatever is thrown your way out on the track.
