Sonnax mechanical diode one-way clutch FD-MD-2 offers much greater strength than existing roller clutches and dog-bone style sprags. The mechanical diode is ideal for high-horsepower drag racing vehicles. Sonnax offers the FD-MD-2 for applications with the Ford 10" Falcon stator. Made from hardened S7 steel, the FD-MD-2 features the Ford 32-tooth spline.
This unique design for a one-way clutch assembly known as the "Mechanical Diode®" (MD) was developed by Epilogics, Inc. in 1991 and was first introduced to torque converter rebuilders by Sonnax in 1997. The MD overrunning clutch, or freewheel, offers much greater strength than existing roller-ramps and sprags.
