Racing Torque Converter Features:

Anti-Balloon Plates

We add specially made anti-balloon plates to the flanged hubs to further reinforce the overall outer strength of your torque converter. This makes it almost impossible for the torque converter to balloon out and lose the inner dynamic flow.

Billet Cover

The billet cover option is standard for all high performance racing converters and is available as an option for some street performance racing converters.

Torque Converter Balancing

Whether a converter is welded or furnace brazed, your converter NEEDS to be REBALANCED INSIDE and OUT for peak efficiency and to eliminate any vibration. Most competitors do not even have the balancing equipment!

Precision of New Hampton is the ONLY COMPANY IN THE INDUSTRY that balances each individual part to within 1 gram. Balancing issues can cause metal fatigue, efficiency loss, horsepower loss and inevitable early torque converter failure.

Furnace Brazing

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?

Hardened Turbine Splines

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 ...


Precision of New Hampton uses hardened turbine splines, virtually eliminating a major reason for torque converter failure. 90% of the time, it happens right at the starting line. The input splines on the transmission 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 put you at a disadvantage in the long run.

High Performance Stators

Precision of New Hampton installs a redesigned stator to give you maximum torque multiplication equaling more horsepower to your tires.

Trade Secrets

Precision’s racing side performs many other unique applications while building racing converters. The competitors DON’T; and, consequently, Precision of New Hampton has patented the process on these special practices.

Those features combined with UNBEATABLE CUSTOMER SERVICE are what makes our racing converters the ONLY CHOICE for your race car.

Torque Converter Reinforcing

Precision of New Hampton wants your converter to last as long, if not LONGER than the rest of your ride. Bearing that in mind, another option offered is converter reinforcement. An EXTRA metal reinforcement plate is added to the converter. This plate, in conjunction with our anti-balloon plate, gives a Precision made racer that "extra edge" in preventing ballooning of the converter under the most EXTREME conditions.

Multi-Roller Sprag

A multi-roller sprag is a high performance replacement for the regular sprag that is more often installed. It encapsulates all parts tighter with VERY strict quality control. The main motivation for a multi-roller sprag, versus a regular sprag, is greater durability and increased vehicle response time. The multi-roller sprag does not contribute to any loss of speed, a spragless converter does.

Friction Disc System

Precision of New Hampton’s friction disc clutch is the ultimate option when building a converter that will TRULY stand above the rest.

The friction disc retains lockup for efficiency without durability issues and will virtually ELIMINATE SLIPPAGE by providing a vastly increased clutch surface.

Did you know that slippage is one of the main causes of transmission failure? That’s right, every time the clutch slips, the clutch surface becomes HOTTER, eventually causing the surface to glaze over and become VERY SLIPPERY and VERY BRITTLE. When the clutch surface becomes more and more slippery, the clutch slips EVEN MORE. The eventual brittleness leads to tiny pieces breaking away—and where do they go?

That’s right. The clutch debris passes through to the transmission and eventually, with enough pieces, your transmission will break down, causing costly repairs. Precision of New Hampton’s FRICTION DISC CLUTCH, while giving you optimal performance, SAVES YOUR TRANSMISSION as well!

When you want to be the fastest - Go With The Blue!

We have been put to the test again and again.

If you are trying to get the most performance out of your transmission, we are your pick. With our advanced manufacturing processes we can keep transmission temps low ensuring longevity and power. Most transmission issues with high performance transmissions are due to the torque converter heating up the fluid with friction exceeding max temps. With our rigorous testing and ability to manufacture our own parts, you will notice a night a day difference compared to our competitors.
