Diamond T FT08ST Triple Disc Torque Converter for 2008–2010 Ford 6.4L Powerstroke (5R110W)
Replace a worn or slipping converter behind the 5R110W TorqShift with a heavy-duty triple disc unit built for stock-horsepower 6.4L trucks. Diamond T remanufactures each FT08ST from its own matched set of original components.
Key Benefits & Features
- Triple Disc Clutch: Triple disc lockup clutch in a heavy-duty design, built to hold under the load of a working 6.4L.
- Stock Power Rating: Built for stock-horsepower trucks, so it drops in as a direct replacement without changing how the truck drives.
- Matched-Parts Rebuild: Original components stay together through the rebuild, and marginal parts are replaced.
- Housing Checked to OEM Spec: Housing thickness is measured, and a housing under OEM spec is replaced instead of being machined thin.
- Balanced and Tested: Each converter is computer balanced and quality tested, then pre-charged with fluid to keep the internals from rusting before install.
- Warranty: Lifetime, non-transferable Diamond T warranty against defects in material and workmanship.
Fitment
- 2008–2010 Ford F-250, F-350, F-450 and F-550 Super Duty 6.4L Powerstroke Diesel with the 5R110W automatic
- Part Number: Diamond T FT08ST
Tech & Installation Notes
- Higher Power: For tuned trucks making well above stock power, Diamond T builds 650 HP-rated 6.4L converters instead.
- Warranty Terms: Coverage is replacement of the converter only and does not include labor or other parts.

Stock stall and yes.
Q
Gabe • 10/12/2026, 6:42:52 PM
Does this have 8 studs on the converter to mount to the flex plate
A
10/13/2026, 1:13:29 PM
Yes, it does.
The Diamond T FT08ST torque converter features an 8-stud front cover pattern, matching the factory 8-stud flexplate configuration used on 2008–2010 Ford 6.4L Powerstroke / 5R110W applications.
(In contrast to the earlier 6.0L Powerstroke 5R110W setups, which typically use a 6-stud pattern, the 6.4L-specific FT08ST comes standard with 8 studs).
