5R110W Torque Converters

High-Performance 2008-2010 6.4 Powerstroke 5R110W Torque Converters

The torque converter is the critical mechanical and hydraulic link responsible for transferring the immense power of your 2008-2010 Ford 6.4L Powerstroke from the crankshaft directly into the 5R110W TorqShift automatic transmission. While the factory converter functions fine for a completely stock truck under light loads, it is an absolute bottleneck once you start utilizing the true performance potential of the common-rail 6.4L platform. The factory torque converter features a single, vulnerable friction disc clutch and a stamped-steel front cover. When subjected to the aggressive, instantaneous torque gains of custom tuning, heavy-duty towing, or boosted 4x4 launches, the stock converter clutch will slip, overheat, and warp. This leads to severe converter "shudder," high transmission fluid temperatures, and eventual internal ballooning that can send destructive metallic debris directly through your entire pump assembly and valve body.

Upgrading to a heavy-duty aftermarket torque converter is one of the most critical drivetrain modifications you can make for your 6.4L Super Duty. Replacing the fragile factory unit secures your power transfer, ensuring your twin sequential turbochargers can spool up efficiently and put maximum power down to the ground without destroying your transmission internals.

At Full Force Diesel, we carry an extensive inventory of premium, engineered torque converters designed specifically to handle the high-torque demands of the 2008-2010 6.4 Powerstroke:

• Heavy-Duty Triple-Disc Assemblies: Multiply your mechanical holding power. We stock premium multi-disc torque converters from industry leaders like Revmax, BD Diesel, and SunCoast. Featuring three independent friction surfaces instead of the factory single disc, these units guarantee a positive, blowout-proof lockup that handles high-horsepower street files and heavy towing with ease.

• Billet Steel Front Covers: Eliminate structural ballooning permanently. Performance aftermarket converters feature CNC-machined billet steel front covers that will not flex, warp, or distort under high internal hydraulic line pressures, keeping your internal clearances perfect and your lockup crisp.

• Optimized & Custom Stall Speeds: Match your converter to your specific driving habits and turbo configuration. Whether you need a tight, low-stall converter to lower fluid temperatures and maximize low-end torque for heavy trailer pulling, or a slightly higher stall speed to efficiently spool large aftermarket turbo arrangements, we have the exact stator design you need.

• Reinforced Internal Construction: Built for ultimate durability. These heavy-duty converters feature furnace-brazed or TIG-welded impeller and turbine fins, along with hardened billet steel turbine hubs and heavy-duty torrington bearings to replace factory plastic thrust washers.

Don't let a slipping factory converter clutch or annoying drivetrain shudder limit what your Super Duty can haul. Whether you are building a high-boost street machine or bulletproofing a dedicated daily tow rig, we have the heavy-duty drivetrain components you need.
