Firepunk 10L1000 Hard Anodized F-Clutch Drum

Firepunk 10L1000 Hard Anodized F-Clutch Drum – Extended Service Life Upgrade

If you’ve serviced the 10L1000 transmission, you may have already encountered accelerated wear on the factory F-clutch drum. Unlike earlier Allisons that used steel drums, the 10L1000 features a lightweight aluminum drum that can’t always keep up with the demands of tuned trucks and heavy use. Over time, the clutch steels begin to erode the channels in the drum, leading to poor clutch engagement, incomplete shifts, or even tie-ups between ranges.

The Firepunk Solution

After extensive testing in customer trucks under real-world conditions—from high-mileage tow rigs to street-driven performance builds—our upgraded F-clutch drum has proven itself time and time again. We’ve seen excellent results in durability and shifting consistency, and we’re now excited to officially bring this upgrade to market.

This precision-machined drum features a hard anodized surface treatment to significantly increase wear resistance compared to the OEM aluminum design. It’s built to hold up under increased load and extended use, making it the go-to solution for any 10L1000 application that demands more than stock.

Features:

• Direct replacement for GM 24048634

• Includes XCalliber Steel Splined Insert for F Clutch Pack

• Hard anodized for superior wear resistance

• Includes Ring Gear for the Output Shaft Planetary

• Includes Ring Gear Snap Ring

• Built to handle increased clutch load without premature failure

Whether you’re towing, racing, or daily driving, this is the F-clutch drum your 10L1000 should have had from the start.
