Thumbnail Filmstrip of 2011-2019 6.7L Powerstroke 1900 RPM Billet Quadralock Torque Converter Suncoast 6R140-2 Images
The Suncoast 6R140-2 is a 1900 rpm stall billet torque converter for 2011-2019 Ford Super Duty trucks with the 6.7L Powerstroke and 6R140 automatic. Once power climbs past stock, the factory converter clutch is a common slip point, and a slipping clutch builds heat and wears the transmission fluid fast. This converter is built for a mildly upgraded turbo that still tows heavy, with quicker spool off the line.
The Quadralock captured clutch design does not need to exhaust fluid from the back of the apply piston, so the clutch applies faster than a conventional converter, and a larger apply piston adds over 1,000 psi of clamping force. It matches the 6R140-1 except for a custom stator that adds roughly 200-300 rpm of stall, landing near 1,900 rpm for quicker spool while still pulling heavy loads with stock-like drivability. Core required, refundable deposit at checkout.
Key Features & Benefits
- Quadralock Captured Clutch: Higher clutch count and quicker apply rates hold lock-up under heavy load.
- ADCCT Anti Drag Technology: Cuts clutch drag when the converter is unlocked.
- Billet One-Piece Cover: CNC machined billet forged cover with a 4140 HTSR billet steel clutch retaining ring.
- Billet Stator and Upgraded Sprag: Custom stator for efficiency and a stronger sprag for hard launches.
- Furnace Brazed Fins: Fins stay put under high torque and heat, with a Torrington thrust bearing design.

Vehicle Fitment & Technical Installation Notes
Fits 2011-2019 Ford Super Duty with the 6.7L Powerstroke and 6R140 automatic transmission, for use with the 6-bolt flex plate.
Installation Tip: Fill the converter with fresh fluid before installing, and make sure it is fully seated on the pump with proper clearance to the flex plate before bolting the bell housing up. Never use the converter bolts to pull it forward, and flush the cooler lines so debris from the old converter does not end up in the new one.
