The FTI-F2575C reverse cutch pack pressure plate retaining ring. This is the snap ring that locks into the groove in the case and locks the reverse pressure plate into the case. The end gap design of this ring is a different configuration than the OEM design but offers excellent locking power.
Based on our experience with the FTI-F2575C, the snap ring is a little harder to installed and remove than an OEM design snap ring but does function very well.
