GM Turbo 350 Torque Converter

3800-4200 Stall

1968-1981 TH-350, 10.5" bolt circle, non lock up

This Assault Racing torque converter works great in performance street / strip modified small and big block engines with a stall speed of approximately 3800 to 4200 RPM depending on application. Converter is approx. 10" in diameter with a 10.5" flexplate bolt pattern.

Welded not Furnace Brazed. Contrary to popular belief, furnace brazing is not the best way to adhere torque converter components to together. Just like a Teflon coated pan, after some time the furnace brazing will erode away and ruin the stators and all other rotating parts in your transmission.

Industrial Bearings - No Light Duty Needle Bearings. Needle bearings are good, but not great. Industrial bearings give these converters the ability to handle not hundreds, but thousands of pounds of torque. That’s much better then the higher priced alternative converters.

Aircraft Aluminum Washers - NO FIBER. Assault converters utilize an aircraft quality aluminum washer instead of those old fiber washers that other companies use. This allows for more horsepower and torque capabilities.

NO Automation - ALL HAND BUILT. Assault torque converters are hand built and tested to ensure that you are getting the best converter money can buy. No automated process can ensure that you will get that kind of quality. Made here in the USA.

Torque converter fit and application is 100% the responsibility of buyer.
