Thumbnail Filmstrip of 6.7 Powerstroke 10R80 Cat 2 Rebuild Kit with Extra Capacity Clutch Packs Suncoast SC-10R80-CAT2 Images
Maximize the performance and longevity of your 2017–2021 6.7L Powerstroke with the revolutionary Suncoast SC-10R80-CAT2 10R80 Cat 2 Rebuild Kit with Extra Capacity Clutch Packs. The Ford 10R80 10-speed automatic transmission, a product of a unique collaboration designed to meet stringent fuel economy and emissions mandates, is an advanced unit built to handle the power of vehicles like the Mustang GT and F-150 Raptor while boosting the efficiency of the Expedition and Navigator. It's engineered to mimic the efficiency benefits of a continuously variable transmission (CVT)—which maintains optimal engine speed—by utilizing a wide 7.39 gear ratio spread and incredibly small steps between the gears. This design ensures that the engine RPM only drops approximately 20% with each shift, keeping your engine constantly within the ideal power band for either peak performance or superior efficiency. This shift recovery allows for the use of larger camshafts in naturally aspirated setups or larger turbos and A/R housings in forced-induction applications, extracting maximum potential from your engine. However, even this advanced transmission has weaknesses when pushed beyond stock limits, particularly in the highly-stressed "D," "E," and "F" clutch packs, which is precisely why the Suncoast Cat 2 kit is essential for demanding driving.
- This complete clutch and steel module kit is specifically engineered to eliminate common weak points in the Ford 10R80 transmission for 6.7L Powerstroke 2017–2021 models, providing unparalleled durability and performance:
- Extra Capacity "E" Clutch Module: Increases capacity by a whopping 20% (from 5 to 6 clutches). This completely assembled, drop-in replacement includes a new OE-machined drum, piston, and backing plate to combat premature failure from the "E" clutch's constant on/off cycling in lower gears.
- Expanded Capacity "F" Clutch Pack: Boosts capacity by 25% (from 4 to 5 clutches) to address the rapid degradation seen in this pack, especially during heavy-load or wide-open-throttle 3rd -to-4th shifts where torque management is deleted.
- Upgraded "D" Clutch with GPZ Friction: Uses Raybestos Powertrain GPZ friction material to provide higher friction coefficients and increase torque capacity well beyond factory limits, addressing rapid degradation from the clutch's responsibility as an oncoming clutch in 6th gear.
- Raybestos GPZ Frictions & Steels: The entire kit utilizes state-of-the-art GPZ friction plates, which withstand high stress and temperatures, outperforming OE materials by as much as 20% and providing greater torque capacity, enhanced shift feel, and smooth engagements.
- New Factory Thermal Flow Control Filter: Includes a new OEM filter with a revolutionary design that uses both coarse and fine media separated by a thermal plate. When the fluid heats up, the plate restricts the coarse section, forcing fluid through the fine media for superior debris filtration, ensuring zero flow issues.
- High-Performance Overhaul Kit: Contains all necessary frictions, steels, and components for a comprehensive rebuild.
By incorporating the latest advancements in friction technology and addressing the critical design deficiencies with its expanded-capacity modules—requiring absolutely no machining for installation—the Suncoast SC-10R80-CAT2 rebuild kit transforms the capable factory 10R80 into a robust, high-performance unit. This upgrade is not just a replacement; it's a vital performance enhancement that ensures your transmission can reliably handle the increased demands of a modified or heavily-used 6.7L Powerstroke, offering greater torque capacity and exceptional longevity. Trust Suncoast and Raybestos to deliver the most reliable 10R80 performance upgrade to date.
