Chrysler 904 Torque Converters
Performance Torque Converters for TorqueFlite 904 Transmissions
The Chrysler 904 is a popular choice for lightweight Mopar street and performance builds where efficiency, packaging and performance all matter.
Boss Hog 904 torque converters are available for combinations ranging from mild street vehicles to modified street/strip applications.
Choosing the appropriate converter requires looking at the engine, camshaft, transmission, vehicle weight, rear gear, tire diameter and intended use together.
If your Mopar has been modified since the current converter was installed, it may be time to reconsider the converter as part of the complete drivetrain.
