Deliver Power Where You Need It Most

The ATS 302-950-4368 Five Star Torque Converter is designed specifically for Allison-equipped GM Silverado and Sierra 2500HD/3500HD trucks. With a stall speed set between 1300 and 1500 RPM, it helps deliver smoother launches and better low-end torque without sacrificing efficiency. This makes it perfect for trucks that need to move heavy loads while keeping engine response crisp and predictable. ATS’s proven Five Star Viskus Drive design ensures reliable power transfer under load, making your truck feel stronger and more connected to the pavement.

Built with a billet F-Trim stator and a positive impeller, this converter is designed to hold up under the stress of towing, heavy hauling, or daily driving with added horsepower. The billet construction adds strength where factory converters often fail, giving you confidence whether you’re climbing hills with a trailer or just navigating traffic with a tuned setup. It’s a direct replacement that works with your factory Allison transmission, making it a perfect upgrade for anyone looking to improve drivetrain performance without unnecessary complexity. If you’re serious about getting the most out of your Duramax-powered truck, this ATS torque converter delivers the durability and performance you’ve been looking for.
