With a stall speed of 1,700 to 1,800 RPM, it delivers the perfect balance between low-end drivability and performance, especially for trucks with stock or mildly upgraded turbos. Whether you're pulling heavy loads or merging onto the highway with a trailer in tow, this converter keeps your powerband tight and your transmission locked in. The triple disc clutch ensures firm engagement and minimal slip, giving you confidence under throttle without sacrificing comfort on the street. It's also a smart move if you’re planning to upgrade later and want a converter that’s ready for more. Like all SunCoast torque converters, it’s designed and built in-house to exacting standards, so you know you're getting proven quality with every unit. If you want to improve drivability without jumping into full race-spec parts, this is the upgrade that makes sense.\u003c\/p\u003e\n\u003ch4\u003eBuilt For Torque Control And Long Haul Strength\u003c\/h4\u003e\n\u003cp\u003eThe SunCoast GM-1057-3D Triple Disc Torque Converter is engineered for 2001–2016 GM 2500HD and 3500HD trucks equipped with the Allison 1000 transmission, offering a durable and balanced solution for towing and street performance. It features a 1,700–1,800 RPM stall speed, which is ideal for maintaining turbo efficiency while preserving low-speed control and towing capability. Internally, it’s built around a triple disc lockup clutch system for improved holding power and reduced slip, making it highly efficient under throttle. A forged billet steel cover adds structural strength, while the billet stator resists internal damage during high-load conditions like extended brake stalling. These details make it a solid match for drivers who need dependable lockup and performance without jumping to a high-stall race converter. This unit is especially useful for builds with minor tuning, towing packages, or mild turbo upgrades. Manufactured entirely in-house by SunCoast, this converter ensures consistent performance, tighter lockup control, and increased drivetrain reliability for long-term use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2001–2016 GM 2500HD\/3500HD 6.6L Duramax trucks\u003c\/li\u003e\n\u003cli\u003eDesigned for use with Allison 1000 transmissions\u003c\/li\u003e\n\u003cli\u003eStall speed is set between 1,700 and 1,800 RPM\u003c\/li\u003e\n\u003cli\u003eIdeal for stock or mildly upgraded turbo setups\u003c\/li\u003e\n\u003cli\u003eRecommended for towing, daily driving, and light performance\u003c\/li\u003e\n\u003cli\u003eTriple disc lockup improves holding power and efficiency\u003c\/li\u003e\n\u003cli\u003eBillet stator resists damage from extended brake stalling\u003c\/li\u003e\n\u003cli\u003eForged billet steel cover adds structural durability\u003c\/li\u003e\n\u003cli\u003eBuilt in-house by SunCoast for quality and consistency\u003c\/li\u003e\n\u003cli\u003eNot intended for high-stall race applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":68060762833169,"sku":"SUN-GM-1057-3D","price":1799.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/SUNSUNGM-1057-3D_20TORQUE_20CONVERTER_2000.jpg?v=1794724075","url":"https:\/\/gautoparts.com\/products\/suncoast-gm-1057-3d-triple-disk-torque-converter-01-16-gm-6-6l-duramax","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
