The Perfect Balance Of Street Manners And Towing Muscle

If you want your Powerstroke to feel more responsive without sacrificing the ability to tow heavy, the SunCoast 6R140-2 Street and Tow Torque Converter hits that balance perfectly. This converter is built for trucks that live on the road but still see real work on a regular basis. Throttle response improves right away, making the truck feel lighter and more eager to move. Turbo spool comes on quicker, which is especially noticeable when pulling away from a stop with a trailer. Even with the added stall speed, drivability remains smooth and predictable in everyday traffic. It feels natural, not aggressive or jerky, which is exactly what most daily driven trucks need. Whether you are cruising around town or hooked up to a heavy load, this converter simply makes the truck more enjoyable to drive.

Advanced Lockup Technology Designed For Real World Use

The SunCoast 6R140-2 Street and Tow Torque Converter is designed for 2011-2019 Ford F250 and F350 trucks equipped with the 6.7L Powerstroke and 6R140 transmission. It features SunCoast captured clutch lockup technology, which operates differently than conventional torque converters. By eliminating the need to exhaust fluid from behind the apply piston, the converter achieves faster and more efficient lockup engagement. Compared to a factory converter, this design delivers quicker response and improved efficiency under load. A custom stator provides an additional 200 to 300 RPM of stall speed, improving turbo spool without compromising towing capability. Despite the increased stall, drivability remains very similar to stock. This converter is ideal for trucks with mild turbo upgrades that still need dependable towing performance.
