Some of the first steps of designing new products is by identifying the weak points and problem areas of the existing parts and figuring out how to improve and fix them. In the case of the Ford 4R100 torque converter, the main factory components are the weak points. The impeller and turbine being made of thinner steel, and the lack of furnace brazing on the turbine, leaves these parts prone to breakage and catastrophic converter failures.

Rather than try to put a bandage on these weaknesses, Goerend sets the stock Ford torque converters aside and looked to the stronger, more reliable Allison 1000 torque converter. Using the Allison 1000 furnace brazed turbine and impeller, Goerend is able to produce the highest strength 4R100 torque converter.

Stators are only as strong as their weakest link. Other aftermarket converter manufacturers may use a billet stator, but will also use the weak factory one-way roller clutch designed for stock horsepower applications. The stock factory inner and outer races that make up the one-way roller clutch can barely hold up to stock conditions and can easily crack or strip out in medium to high horsepower applications. When this happens, the stator will start to freewheel and the converter will lose all torque multiplication. A damaged stator race will also greatly reduce vehicle drivability. 
Along with our billet aluminum stator found in all of our Ford converters, we utilize lugged outer races that will not strip out. Both the inner and outer races are wider and more substantial than OE to increase surface area and holding power, while preventing cracking failure. The steel outer ring is pinned to the stator, preventing it from being displaced and destroying the converter.
