Cummins Maincaps

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
