Make Every Ounce Of Torque Count At Launch

When your Duramax is built to haul, race, or spool up a big turbo, you need a torque converter that can actually keep up. The SunCoast GM-1071-3D Speed Torque Converter is designed to put all your power to the ground with precision lockup and unbeatable strength. Whether you're drag racing, sled pulling, or just need dependable lockup for towing heavy loads, this converter gives you the confidence to push harder without fear of failure. It’s built with a triple disc lockup clutch and a forged billet steel cover, giving you the durability needed to handle big torque under pressure. Higher stall speeds are available, which is perfect for builds running larger turbos that need more RPM to hit boost. With its in-house design and manufacturing, SunCoast ensures consistent quality and real-world-tested performance. This isn't just a stronger converter, it’s a smarter upgrade built for how real truck owners drive.

Built For High Power And Hard Launches

The SunCoast GM-1071-3D Torque Converter is engineered specifically for the Allison 1000 transmission found in 2001–2016 Duramax-equipped Silverado and Sierra HD trucks. It features a triple disc lockup system for superior clutch engagement and reduced slippage under heavy load, making it ideal for high-horsepower applications. The billet stator is built to withstand damage from prolonged brake stalling, a common risk in race or pull scenarios where stall times exceed five seconds. A forged billet steel front cover ensures maximum durability and rigidity under extreme torque and heat. SunCoast also offers custom stall speed options to match your setup, especially helpful for builds running oversized turbos that require more RPM to build boost effectively. Every converter is designed, machined, and assembled in-house to meet exacting performance standards. Whether you're building a weekend warrior or a full-on race truck, this torque converter provides the control and strength your Allison transmission needs.
