The Converter That Makes Your Truck Feel Alive Again

If your Powerstroke feels lazy off the line after upgrading the turbo or adding power, the SunCoast Billet Quadralock Torque Converter is the fix that brings everything back into balance. This converter is designed for drivers who want quicker response without sacrificing the ability to tow heavy. Throttle input feels more immediate, and the truck spools faster, which makes merging, passing, and even spirited driving far more enjoyable. Despite the increased stall speed, everyday drivability remains smooth and predictable, just like stock. That balance is what makes this converter such a great match for street driven trucks that still see real work. It shines when towing heavy loads but really comes alive when you put your foot down. For owners running a slightly larger turbo, this converter helps unlock the performance you already paid for.

Advanced Lockup Design Built For Control And Efficiency

The SunCoast 6R140-3 Billet Quadralock Torque Converter is designed for 2011-2019 Ford F250 and F350 trucks equipped with the 6.7L Powerstroke and 6R140 transmission. This converter uses a captured clutch design that operates differently than conventional torque converters. By eliminating the need to exhaust fluid from behind the apply piston, lockup engagement happens much quicker and more efficiently. Compared to the 6R140-1 version, this model features a custom stator that adds approximately 200 to 300 RPM of additional stall speed. This increase improves turbo spool while maintaining strong towing performance and stock-like drivability. The billet construction enhances durability under higher torque loads. It is an ideal solution for trucks with upgraded turbos that still need dependable towing capability.
