Transmission Pan Gaskets have a glass-filled nylon or metal carrier with reusable silicone molded on the top and bottom. These are the same materials in many modern production engines. Plus, future transmission service will be easy because the old gasket won't need to be scraped off and replaced each time you drop the pan. Clean-up is simple with soap & water.
Heavy-Duty 4340M alloy steel Input & Output Shafts are ideal for high-horsepower applications. Also known as 300M, this type of alloy can be hardened to a greater thickness when compared to other steel blends, resulting in its use in aerospace and other areas where high-strength gears, axles, and spindles are required. JEGS offers shaft options for a variety of transmissions.
