Standard Features

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, Inc. 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
Triple Disc System

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?

Trade Secrets

Precision racing side performs so many other unique applications while building racing converters. The competitors DON'T and consequently, Precision 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.

Optional 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
Precision Triple Disc Billet Cover

Billet Cover option is standard for all High Performance Racing Converters and is available as an option for some Street Performance Racing Converters.

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 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 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.
