DODGE 17SS

Used for light to heavy towing. This converter stall is equivalent to a stock converter stall.

This converter works well with:
2nd generation Dodge with 60 - 62mm turbos at 0 - 4,000 ft elev.
3rd generation Dodge with 63 - 71mm turbos.
67 - 71mm turbos at 0 - 4,000 ft elev.
63 - 66mm turbos at 0 - 11,000 ft elev.

DODGE 17-250

This converter will be approximately 300 RPM looser than stock. It is a higher stall to help get large turbos spooled. This stall is not recommended for towing.

DODGE 15SS

The most versatile converter. Loose enough to spool most turbos, in most elevations and climates, while maximizing low end grunt and keeping the torque converter tight enough when the turbo lights and horsepower is created. This converter should go in trucks that tow and work hard. Approximately 200 - 400 RPM lower than a stock converter.

This converter works well with:
OE turbos at 0 - 11,000 ft elev.
2nd generation Dodge with OE - 58mm turbos at 0 - 4,000 ft elev.
3rd generation Dodges with OE - 62mm turbos at 0 - 4,000 ft elev.


FORD E40D/4R100

The Goerend 4FBD stall is excellent for stock to 600+ HP trucks & works with a large range of applications from towing and street performance to daily driving. Stall speed is approximate & will vary based on engine torque. Approximate stall speed of 4FBD is 2000-2200 RPM depending on engine torque.

FORD 5R110

The Goerend 5FBD stall is excellent for stock to 600+ HP trucks & works with a large range of applications from towing and street performance to daily driving. Stall speed is approximate & will vary based on engine torque. Approximate stall speed of 5FBD is 2000-2200 RPM depending on engine torque.

The chart below shows the K factor and torque ratios as related to our converter stalls. Below is how to interpret the K factor and torque ratio numbers. The lower the K factor, the better the converter will couple. The higher the K factor, the easier the converter will spool up. The torque ratio is the torque multiplication number. For example, if a converter has a torque ratio of 1.85, then for every 100 lbs of input torque, the converter will deliver 185 lbs of output torque. This is at a converter stall or speed ratio of 0. This ratio will go down as the speed ratio goes up. Engine modifications will directly affect stall speed. Stall speeds listed below are approximate & will vary based on engine torque.
