Mr. Gasket Inc. is a world-renowned manufacturer of high-performance aftermarket parts. Mr. Gasket was founded in 1964 by the famous drag racer Joseph Hrudka to become the go-to supplier of aftermarket race-approved exhaust gaskets. However, before officially founding the company, Hrudka investigated and developed durable asbestos gaskets to replace the faulty exhaust gaskets that were a major problem for many racers. He sold these parts under the Speed Specialties name in the 1960s before incorporating his company as Mr. Gasket in 1965. From selling high-performance Gaskets in the '60s, Mr. Gasket has become well-known for a wide range of premium products, including but not limited to billet aluminum dress-up components, valve covers, air cleaners, master cylinder covers, shifter knobs, pedals, and ignition wire looms. While the ownership of the company has changed hands several times, Mr. Gasket has withstood the test of time and is still an industry-leading supplier of high-performance aftermarket parts. Now an important part of Holley Performance, Mr. Gasket continues to expand its application coverage with new products for both race cars and muscle cars. Mr. Gasket offers an immense line of products including carburetor and fuel system components. Mr. Gasket has created many industry-first products and set the tone for hot rodder "must-haves" for years.
