ACC 4701HD 12" Heavy-Duty TH-350 Ultra Tow & RV Torque Converter GM Turbo 350

ACC Boss Hog "Ultra Tow" GM Turbo 350 Torque Converter

GM 1968-1981 TH350, 10.5" bolt circle, non lock-up

This ACC Performance Boss Hog "Ultra Tow" torque converter works great in stock to mild performance engines that are used for applications where heavy duty reliability is a must, such as RVs and trucks. Made with extra heavy duty bearings and welding, the Ultra Tow is designed to take the demands of vehicles that do a lot of towing. These have a stall speed of approximately 200 to 300 RPM over stock. 10.5" flexplate bolt pattern.

The automotive industry now has a new torque converter leader. ACC has emerged as a out-right leader in this industry and here’s why:

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. All of ACC torque converters are welded at the seams, not brazed, to eliminate the erosion after time.

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. ACC 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. ACC Performance 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. (You old school people may remember ACC as Alabama Converters).

With all this new information, ask yourself one question. Are you paying too much money for not enough converter? We bet you are. All ACC Performance torque converters are warrantied for a period of 90-Days to be free of defects in material or workmanship under normal operating conditions, providing normal application and installation methods are followed. This warranty does not cover any units that have been tampered with or altered prior to our inspection and is limited to the replacement of the defective torque converter upon inspection.
