12-Inch Triple Disc Billet Torque Converter

The Suncoast SC-4L60E-300MM-LS is an extreme-duty, 12-inch, triple disc, billet torque converter engineered for 4L60E transmissions. This high-performance component is built with a custom CNC'd billet 4140 cover, a billet stator cap, and a billet apply piston, ensuring robust construction for demanding applications. Key features include stronger chromoly steel turbine and impeller hubs for increased strength and reliability, alongside a custom upgraded sprag cartridge offering more than double the original holding capacity. The triple disc design provides three friction surfaces, tripling the surface area, and utilizes woven carbon fiber clutch material for maximum performance. Construction details such as furnace-brazed turbine and pump fins, Torrington roller bearing construction, and Tig-welded pump and turbine fins contribute to its overall durability and efficiency. Built with racing-inspired technology derived from years of track experience, this torque converter delivers unrivaled performance and reliability. The woven carbon fiber clutch material and furnace-brazed fins ensure maximum lockup capacity for efficient power transfer, improving fuel efficiency and performance.
