HOT out of our Manufacturing Department. . . Cummins Maincaps. What a great addition to our Performance Products! Give us a call to purchase yours today. They’re going fast!
Our Maincaps are better and here is why:
- Made out of Ductile Iron, which expands less than steel, with the same strength as 1045 steel
- Works better with Engine Blocks
- Taller eliminating the need for spacers
- Includes a wider Maincap so a Thrust bearing can be used on the bottom side
