Triple Disc Design with Increased Clutch Capacity
This converter provides 200 percent more clutch surface area than a factory version, which improves holding power under load. As a result, it delivers more consistent engagement and better performance in demanding applications. In addition, it supports trucks that operate under regular towing and work conditions without sacrificing drivability.
Billet Construction and Internal Components
The unit includes a billet front cover, which improves strength and long-term durability. Furthermore, it uses Torrington bearings to reduce friction and support smoother operation. These components work together to provide improved efficiency and dependable performance over time.
Stall Options for Different Setups
This converter offers Stock and Low stall options. Stall speed selection depends on your vehicle setup, so choosing the correct option is important. Therefore, if you are unsure which stall speed is best for your application, you should call before ordering.
Fitment and Usage Notes

Why the Torque Converter Is the Most Overlooked Upgrade
Most truck owners focus on power first.
They add tuning, fuel, and air. However, they ignore the one part that actually transfers that power to the ground.
The torque converter.
If it is not doing its job, the truck will feel soft, build unnecessary heat, and never perform the way it should.
The Problem With Factory Converters
Factory converters are built for comfort and cost.
That works fine on a stock truck. Once you start towing heavy or adding power, they quickly become the weak link.
Common signs of a problem include:
- Slipping under load
- Rising transmission temperatures
- Delayed or inconsistent response
Most people chase other issues first. In many cases, the converter is the real problem.
What a Proper Converter Changes
A properly built converter makes an immediate difference.
Power transfers more efficiently. The truck feels tighter. Heat is reduced under load.
Instead of fighting the drivetrain, everything starts working together.
That is the difference between a truck that feels built and one that feels patched together.
One Size Does Not Fit All
Choosing the right converter depends on how the truck is used.
A tow rig needs control and efficiency. A performance build needs strength and proper stall characteristics. A daily driver needs a balance of both.
Getting this wrong leads to frustration and expensive repairs. Getting it right transforms how the truck drives.
Final Thoughts
If you are upgrading your truck and skipping the converter, you are leaving performance on the table.
It is one of the most important parts of the drivetrain, and it directly affects reliability, drivability, and long term durability.

At the end of the day, a torque converter either holds power or it doesn’t. Diesel Performance Converters' torque converters are built to hold.
