Purpose Built For Strength Efficiency And Daily Reliability

The SunCoast 2451816 Single Disk Torque Converter is engineered specifically for 1990–1993 Dodge RAM 2500 and 3500 trucks equipped with the 5.9L 12-valve Cummins engine. Designed and manufactured in-house, this converter delivers improved torque transfer and efficiency through a custom billet stator that increases multiplication prior to lockup. A CNC-machined billet piston provides a stable, flex-free platform for the single disk clutch system, ensuring a reliable lock-up that holds under light to moderate load conditions. The forged billet front cover adds structural strength and durability, making it well-suited for daily driving, towing, and mild performance use. With tighter tolerances and better heat resistance than the factory converter, it’s a dependable option for anyone upgrading from stock. SunCoast’s internal control over design and manufacturing also allows for application-specific tuning, ensuring each unit is matched to the needs of your setup. It’s not just built stronger, it’s built smarter, with a clear focus on reliability and functional performance for real-world driving.
