Sonnax mechanical diode refresher kit GM-MD-RK is used to service Sonnax mechanical diodes with five-strut engagements.
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.
