Forged 7075 Aluminum 10L1000 10 Speed Transmission F Clutch Drum

Replace your stock failure prone 10L1000 F-Drum with this forged 7075 aluminum drum from DHD. This direct replacement F drum is drastically more resistance to channel wear then the OE drum. Its material composition and unique manufacturing processes makes it a premium replacement option for both stock and performance transmission builds.

What is channel wear?

This wear occurs at the interaction between clutch stack and drum. Unlike the steel drum found in your earlier model Allison, the 10L1000 uses a lightweight aluminum drum. As the truck ages the steels of the clutch stack begin to wear away at the channels that hold them, this wear eventually leads to incomplete shifts, range tie ups or catastrophic failure.
