Torque Convertors

Matching a Torque convertor to you engines output is similar to matching a propeller to a boat motor. The pitch is important! The BD Convertor includes bearings in place of the stock bushings. All the fins have been welded in place where only bent fins existed.

The BD Performance Torque convertor has been engineered to more efficiently use the torque developed by the Cummins 6BTA engine.

The stock Allison 500 series torque converter has a stall speed or fluid coupling at 2000 engine RPM. This design misses the peak torque developed by the 6BTA Cummins engine, thus the slipping in the converter.

The BD performance torque convertors has a redesigned stator for improved power and retarding power transfer. A exhaust brake just doesn't seem to work without a BD torque convertor! Exchange convertors are available for the Allison 500 series tranmsission.
