Moroso

<h3>Moroso Performance Products: A Racing Legacy Built Since 1968</h3><p><strong>Moroso Performance Products</strong> has been a cornerstone of American motorsports engineering for more than five decades. Founded in 1968 by Dick Moroso — one of the most accomplished modified production drag racers of his era — the company grew from a passion for wringing every ounce of performance out of a racing engine into one of the world's most respected suppliers of automotive equipment for racing and street performance applications.</p><p>Moroso manufactures over 4,000 products, from oil pans and oiling systems to ignition wire, ignition components, valve covers, fuel system equipment, air cleaners, hard-core racing tools, chassis and suspension equipment, and numerous other performance parts. That breadth of catalog means whether you're building a dedicated drag car, a road-race machine, or a high-performance street driver, Moroso likely has a part engineered specifically for your application.</p><h3>Pioneers of the Deep-Sump Oil Pan</h3><p>Few contributions to performance engine building are as foundational as Moroso's work with oil pans. Moroso pioneered many racing products including deep-sump oil pans, electric water pumps, tall valve covers, lightweight front drag tires, and racing vacuum pumps. The deep-sump concept was born from a simple but powerful insight: keeping oil away from the crankshaft produces more power, because preventing the crankshaft from &quot;sloshing&quot; in oil greatly reduces frictional losses known as &quot;windage.&quot;</p><p>Today, that heritage lives on across a wide range of <a href="/466-moroso-engine-oil-pan-5562">engine oil pans</a> engineered for drag racing, oval racing, road racing, and street/strip use. Whether you drag, oval, or road race, Moroso offers oil pans specially designed for front- or rear-wheel-drive sport compacts, with each pan fully fabricated from aluminum or steel with race-proven features that control oil for maximum power. Moroso also carries a full line of <a href="/466-moroso-automatic-transmission-oil-pan-8546">automatic transmission oil pans</a> that bring the same race-tested philosophy to the drivetrain, helping protect and cool automatic transmissions under demanding conditions.</p><h3>Manufacturing Quality Backed by Decades of Racing Validation</h3><p>The company has an impressive list of customers, ranging from grassroots racers to top-level NASCAR&reg; and NHRA/IHRA race teams. That cross-section of customers — from the weekend warrior to the professional racer — speaks to just how versatile and reliable Moroso products are across the performance spectrum.</p><p>Computers with the latest CAD/CAM software have replaced the drafting tables, and the Moroso plant is filled with sophisticated CNC machinery, including turret punch presses, turning centers, and lathes — a combination of highly skilled craftsmen and accurate machinery that guarantees the tradition of quality started by Dick Moroso in 1968 will continue throughout the coming decades.</p><p>The Connecticut-based manufacturing operation is home to Moroso Performance Products and Competition Engineering – The Chassis People. The company also owns Moroso Wire Technologies, a state-of-the-art ignition wire manufacturing facility in Philadelphia, PA. This vertically integrated approach allows Moroso to maintain tight quality control over every product that bears their name.</p><h3>Why Choose Moroso?</h3><ul style="list-style:disc"><li><strong>Proven racing heritage</strong> dating back to 1968 with innovations still used industry-wide today</li><li><strong>Massive product range</strong> with over 4,000 SKUs covering oiling, ignition, fuel systems, chassis, and more</li><li><strong>Race-to-street engineering</strong> — technologies validated at NASCAR and NHRA events, adapted for everyday performance builds</li><li><strong>Advanced manufacturing</strong> using CNC machinery and CAD/CAM design for consistent, precise fitment</li><li><strong>Wide vehicle coverage</strong> spanning domestic V8 platforms, sport compacts, and everything in between</li></ul>
