AFE 43-12021 F3 Torque Converter
2003-2007 Dodge 5.9L Cummins
The AFE 43-12021 F3 Torque Converter is the answer to putting your power to the pavement. Torque converters are responsible for transferring engine power to the transmission. Single clutch OE torque converters can slip and increase transmission fluid temps. As you add engine performance parts like intakes, manifolds, etc. the factory torque converter’s stall RPM rises thus reducing the available low RPM pulling power. This is where the F3 torque converter comes in. Installing the F3 torque converter will lower your stall speed to as low as 1,200RPM giving you the perfect range for diesel trucks up to 1,000hp. The results of using an F3 torque converter are improved 0-60mph times (by up to 1-second), increases in towing speeds, lower transmission fluid temperatures and a more satisfying driving experience.
Customer Testimonial: “I did not realize how much power was being lost prior to putting this on. In normal driving (empty truck), the acceleration improvement was very noticeable, especially when getting into 4th, 5th and 6th gears, it threw you into the back of the seat; shifts were nice and crisp. When towing my 10,000 lb. trailer, grades that in the past I could barely go 35-40 mph were now easily done at 50-55 mph.” Stuart M.
F3 Torque Converters Feature:
- 3-Clutch System: The F3 Torque converters use a 3-clutch pack assembly which offers up to 3 times the torque capacity of the single clutch OE torque converter. This allows crisper shifts in high gears, smoother power transmission and improved pulling power while reducing transmission fluid temperatures.
- Round Clutch Tips: Round clutch tips are used to optimize fit and clutch wear.
- Stall Speed: 1200 RPM
- Custom Stator: A custom designed stator (with one-way sprag clutch) is used for torque multiplication to stall speed.
- Torrington Thrust Bearing: F3 Converters come with Torrington thrust bearings for maximum strength replacing the stock OE plastic bushings.
- Billet Steel Front Cover: The billet steel front cover is used for increased strength and durability over the factory stamped steel cover. This Billet cover prevents converter ballooning (failure) that is common with OE converters under high torque conditions.
- Brazed Turbine Fins: The turbine fins are responsible for transferring the torque from the engine to the transmission. The F3 turbine fins are brazed for maximum strength even under the harshest conditions and high torque transfer.
- Damping Springs: Damping Springs are used on the clutch assembly for a smooth power transition during acceleration, optimizing your available torque.
- Reinforced Housing: The one-piece stamp forged steel lid uses reinforced ribs for structural support and ultra-high torque capacity.
- Lifetime Warranty: The F3 torque converter comes with a limited lifetime warranty
