Heavy Duty Torque Converters - Precision of New Hampton
Precision of New Hampton has been building Heavy Duty Torque Converters longer than ANY torque converter manufacturer in the business today. We realized a long time ago that OEM Torque Converters in Heavy Duty vehicles couldn't withstand the daily wear and tear demanded by vehicle operators. The torque converters installed in these heavy duty vehicles as original equipment are the same torque converters that are installed in normal use vehicles that use the same transmissions. The result from this poorly matched coupling -- an extremely inefficient, failure prone, and underpowered torque converter.
Precision recognized the problem and took immediate steps to identify and remedy the situation. Our Heavy Duty Torque Converters are DESIGNED WITH HEAVY DUTY USE IN MIND.
Every heavy duty application has different requirements. Precision offers a wide variety of Heavy Duty Torque Converters for every transmission.
Each of our Heavy Duty Torque Converters comes with a standard billet cover. Other available options include our patented Triple Disc System, Heavy Duty Thrust Bearings, Furnace Brazing, and a Billet Steel Flanged Impeller.

We Can HD ANY Torque Converter!
Not all applications require the same stall. That's why Precision can customize your stall to what is going to work BEST for your individual needs.
RV Stall - Lowered 400 RPM from factory.
RV-MAX - Stall Lowered 700 RPM from factory.
The more a clutch surface slips, the hotter and more brittle it becomes. When a clutch surface gets brittle, two things happen: it becomes MORE SLIPPERY and pieces of the clutch surface break away. Once this process starts, there is no reversing it and your converter WILL break down.
By providing multiple clutch surfaces, Precision's Triple Disc Lockup Clutch for your Heavy Duty Torque Converter exponentially increases the clutch surface area inside the converter. This distinctive step is just one more taken to prevent converter breakdown.
The old style needle race bearings in torque converters handle approximately 11,000 lbs. of dynamic thrust pressure.
The 3 sets of the NEW HEAVY DUTY style thrust bearings used by Precision handle 17,000 to 18,000 lbs. of pressure.
That's an increase of about 60-70%.
This special bearing rolls much more efficiently to further eliminate uneven or premature wear, and eventual torque converter failure.
Our furnace brazing process completely laminates the turbine and the impeller.
This effectively makes your converter one piece, leaving no weak link in your converter to cause a failure. The majority of our competitors weld their converters.
Welding only holds at individual spots, creating a converter that is only as strong as its weakest weld. Furthermore, welding changes the flow throughout the converter by causing cavitation or disruption of flow.
Furnace brazing ensures that there is no flexing of the turbine, no more cavitation or disruption of flow, providing more raw power to your tires.
Every tab on a Precision racing torque converter is of equal strength to any other; all due to the furnace brazing process.
A welded converter is only as strong as the weakest weld.
Bottom LIne - Welding in the turbine process results in a DIRECT LOSS of EFFICIENCY and HORSEPOWER.
Is that what you want for you or your customers?
The billet front cover was designed to allow exact perpendicularity between the pilot, mounting pads and the bolt circle.
This is virtually impossible using a stock torque converter cover due to all of the distortion when adding a mounting ring and pilot.
Additionally, the billet cover is designed to allow for more clutch friction contact area - something that is impossible with a stock type front cover.
A billet cover has, on average, DOUBLE THE CONTACT AREA of a stock converter.
Most competitor's performance converters come with turbine splines that have a hardness of 0. This rating is just inadequate for the application and too often, the result .....
IMMEDIATE CONVERTER FAILURE
Precision uses hardened turbine splines, virtually eliminating a major reason for torque converter failure. The input splines on the tranny have a hardness rating of 35 on the Rockwell scale of C; the mismatch with the 0 rating on the turbine shears the splines right off of the turbine.
Another step that the competition skips - a cost cut that will only cost you in the long run.
Did you know...?
...The RV model of Precision's Heavy Duty Torque Converters can save you money on fuel efficiency? In this day and age, where fuel costs are a concern, every little bit helps.
...These Specially Designed Heavy Duty Torque Converters increase the heat dissipation, thereby dropping internal transmission temperature and increasing transmission life.
...On an OEM converter, increased load pressure can cause mounting studs to give, causing cracking.
...Most stock converters used in vehicles with Heavy Duty engines (mainly Diesel Tow applications) have a MASSIVE amount of Slippage. Every time your transmission slips, it is very likely bits and pieces on the inside are breaking away. Those bits and pieces don't just disappear. They go into your transmission. Over time this can cost a LOT of money in transmission overhauls.
