Designed specifically for the 2020-2025 GM 2500HD and 3500HD with the 6.6L Duramax L5P, this converter delivers strength, precision, and reliability in one package. Whether you’re towing at max capacity, hauling through steep grades, or putting down serious power on the track, it’s built to keep pace without missing a beat. By replacing the factory setup with CNC-machined billet components, it ensures more clamping force, smoother shifts, and less slip, which means more of your engine’s power actually makes it to the wheels. Every part of this converter has been designed to withstand extreme conditions while keeping drivability refined for everyday use.\u003c\/p\u003e\n\u003ch4\u003eEngineering That Doesn’t Cut Corners\u003c\/h4\u003e\n\u003cp\u003eThis torque converter isn’t just heavy-duty in name, it’s engineered from front to back with durability in mind. The billet apply piston, front cover, and stator are CNC machined for unmatched strength and precision, while furnace-brazed turbine and pump fins prevent failure under high loads. A 4140 HTSR billet hub and turbine spline provide the backbone for long-term reliability, and the triple disc clutch design offers 33% more apply area than the factory unit, translating to improved holding power under boost. The higher-friction clutch material means less slippage, keeping temperatures lower and efficiency higher. Even the assembly process reflects the quality: each converter is hand-built in the USA, tested, and backed by a 3-year unlimited mileage warranty. Install it, and you can expect not just better performance, but confidence that your transmission is ready for whatever you throw at it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e 2020, 2021, 2022, 2023, 2024, 2025 GM 2500HD\/3500HD 6.6L Duramax L5P\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCore charge of $2,000 applies.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":51169232847132,"sku":"SUN10L1000-XD-3D","price":2226.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/SUN10L1000-XD-3D_1.jpg?v=1755037078"},{"product_id":"suncoast-10l1000-xd-3d-extreme-duty-allison-10-speed-triple-disc-billet-torque-converter-2020-2025-gm-2500hd-3500hd-6-6l-duramax-l5p-copy","title":"SunCoast 10L1000-6X-3D Allison 10L1000 10 Speed Triple Disc Billet Torque Converter (Stock Stall) | 2020-2025 GM 2500HD\/3500HD 6.6L Duramax L5P","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2020–2025 GM 2500HD and 3500HD Duramax\u003c\/li\u003e\n\u003cli\u003eDesigned for Allison 10L1000 10-speed transmissions\u003c\/li\u003e\n\u003cli\u003eTriple disc billet design for maximum durability\u003c\/li\u003e\n\u003cli\u003eReduces turbine slip under heavy load\u003c\/li\u003e\n\u003cli\u003eImproves towing efficiency and heat control\u003c\/li\u003e\n\u003cli\u003eCNC machined billet stator and piston assembly\u003c\/li\u003e\n\u003cli\u003e4140 steel turbine and impeller hubs\u003c\/li\u003e\n\u003cli\u003eFurnace brazed fins for increased strength\u003c\/li\u003e\n\u003cli\u003eEnhanced clutch material for faster lockup\u003c\/li\u003e\n\u003cli\u003eNew billet cover resists deflection under pressure\u003c\/li\u003e\n\u003cli\u003eHand assembled in the USA\u003c\/li\u003e\n\u003cli\u003eBacked by 3-year unlimited mileage warranty\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eBuild Your Duramax Into A Tow Ready Powerhouse\u003c\/h4\u003e\n\u003cp\u003eIf you’re pushing your L5P harder than the factory ever expected, the SunCoast 10L1000 Triple Disc Billet Torque Converter is one of the smartest upgrades you can make. It transforms the way your truck handles heavy loads by cutting down turbine slip and delivering a stronger, more consistent lockup feel. This means smoother towing, cooler temperatures, and far less strain on the rest of your transmission. You’ll feel the difference the first time you put your foot into it with a trailer behind you, because the converter grabs sooner and holds stronger without the mushy hesitation the stock unit can develop. SunCoast builds this converter with a full billet stator, billet piston, and billet cover, so you’re getting the strength your truck needs for real work. It’s designed to stand up to aggressive driving, added power, and long hauls without giving up reliability. If you want a torque converter that feels tighter, pulls harder, and lasts longer than stock, this one is built for that exact purpose.\u003c\/p\u003e\n\u003ch4\u003ePrecision Built Converter Engineering For Serious Power Levels\u003c\/h4\u003e\n\u003cp\u003eThe SunCoast 10L1000-6X-3D Converter is engineered specifically for 2020–2025 GM 2500HD and 3500HD trucks equipped with the Allison 10L1000 transmission. This unit addresses the weak points commonly found when these trucks are pushed above factory power levels by reducing turbine slip through a CNC machined billet stator that improves efficiency and heat control. The triple disc clutch setup features upgraded friction material with increased surface area, allowing the converter to engage more effectively under load while reducing lockup times. SunCoast also upgrades the impeller and turbine hubs to CNC machined 4140 steel to eliminate deflection and improve long term strength. A billet apply piston and billet cover work together to add clamping force and maintain consistent apply pressure, even under demanding conditions. The fin assembly is furnace brazed for added rigidity, ensuring the converter holds up during long towing cycles and hard accelerations. Each unit is hand assembled and tested in Florida, backed by a 3 year unlimited mileage warranty for confidence in real world use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2020-2025 GM 2500HD\/3500HD 6.6L Duramax L5P\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 2020–2025 GM 2500HD and 3500HD with 6.6L Duramax L5P\u003c\/li\u003e\n\u003cli\u003eBuilt specifically for the Allison 10L1000 10-speed transmission\u003c\/li\u003e\n\u003cli\u003eIntended for use in high power and heavy towing applications\u003c\/li\u003e\n\u003cli\u003eRefundable core charge of $2,000.00 applies\u003c\/li\u003e\n\u003cli\u003eCore must be returned in acceptable condition to receive refund\u003c\/li\u003e\n\u003cli\u003eHelps address turbine slip and clutch failure at higher output\u003c\/li\u003e\n\u003cli\u003eNot recommended for vehicles running a stock transmission tune under factory load levels\u003c\/li\u003e\n\u003cli\u003ePairing with transmission tuning is recommended for optimal performance\u003c\/li\u003e\n\u003cli\u003eHand assembled and quality inspected in Ft.
