About Magnum Gaskets
Magnum Gaskets is a U.S.-based aftermarket brand with roots that run deeper than most. Launched under Modern Silicone Technologies (MSI), a domestic contract manufacturer that has been supplying high-tech molded gaskets to major OEMs and leading aftermarket brands since the mid-1990s, Magnum brings genuine factory expertise directly to the repair shop and the enthusiast garage. Where many brands source gaskets from outside suppliers, Magnum's heritage is in making the very gaskets those other brands sell.
The Magnum product line spans all the major engine sealing categories — intake manifold gasket sets, head gaskets, head sets, exhaust manifold sets, valve cover sets, oil pan sets, timing cover sets, rear main bearing seal sets, and more. Coverage runs from 1955 through current model years, embracing domestic and import vehicles alike, from V8 muscle cars to high-revving import four-cylinders.
One of Magnum's most significant strengths is its manufacturing pedigree. The brand operates under a "USA FIRST" policy, with more than 90 percent of Magnum gaskets designed, manufactured, and packaged in the United States. This allows tight quality control and the ability to deploy the most appropriate gasket construction for each specific application — whether that means multi-layer steel for a modern turbocharged engine or a precision-molded silicone profile for a classic big block.
Magnum has also made deliberate inroads beyond passenger cars and light trucks. The brand covers popular pickup truck diesel applications such as the GM Duramax, Ford Powerstroke, and Dodge/Ram Cummins B Series, and offers more than 100 individually boxed gaskets and seals for medium- and heavy-duty Class 3 through Class 8 diesel truck engines, including Navistar DT466, Caterpillar C7–C15, Detroit Diesel Series 60, and a range of Cummins platforms.
For performance enthusiasts, Magnum's engineering team draws on years of hands-on race and street engine build experience. The Magnum Performance line covers Chevrolet, Ford, and Chrysler small blocks and big blocks, plus GM LS applications, with purpose-built solutions like one-piece molded oil pan gaskets with stroker clearance and their MaxPrint™ intake manifold gaskets featuring stock or race-size ports.
Whether you're refreshing a daily driver, rebuilding a workhorse diesel, or assembling a high-output performance engine, Magnum Gaskets delivers the sealing technology and vehicle coverage to get the job done right the first time. Explore their engine intake manifold gasket sets and individual intake manifold gaskets to find the right fit for your application.
