“MSI is one of the few companies in the world with the huge molding presses required to successfully manufacture the large format, complex gaskets found on today’s diesel engines,” said Alex Grunfeld, president at MSI.

Magnum has released more than 100 new, individually boxed medium- and heavy-duty gaskets and seals for popular Class 3 to Class 8 diesel truck engines, covering Navistar DT466, Caterpillar C7-C15, Detroit Diesel Series 60 and a range of Cummins engines. Magnum’s aftermarket e-Catalog features manifold, valve cover and oil pan gasket sets for pickup truck diesel applications, including GM Duramax V8, Ford Powerstroke V8 and Dodge/Ram/Cummins B Series.


“In high-performance, our gasket engineers have many years of personal experience in street and race engine build-ups,” added Derek Data, vice president at MSI.

One of the new problem-solving products from Magnum Performance is a one-piece molded oil pan gasket (OS84003) for big block Chevy’s that has the side rails trimmed for stroker clearance.

According to MSI, MOPAR fans will appreciate two new 440 molded oil pan gaskets with integral molded plastic windage trays, offered in either a standard depth sump version (OS84011) or with a deep sump (OS84012) for stroker motors. Another Magnum innovation for Chrysler 440s is SP93120 rear main bearing side seals featuring molded silicone rubber on a rigid plastic core for easy installation.
