It's common β especially on tuned trucks. The stock 68RFE OD clutch pack is undersized for Cummins torque when modified.
If you tow heavy or have any Cummins tune, yes β absolutely. We offer heavy-duty OD clutch packs and billet components.
The AS69RC is an Aisin-built alternative β significantly more robust than the 68RFE. If your Ram has it, you're better off.
