Dodge trucks equipped with Aisin Seiki AS68RC transmissions commonly have problems with slipping/flaring in 4th, 5th and 6th Gears, and may lose these ranges altogether. Ratio codes may also be triggered. These issues can often be traced to a damaged K2 hub.

The OE two-piece K2 hub is made from soft, stamped steel which allows the clutch pack to dig into the hub splines, ultimately hanging the clutches up and burning them. Replacement OE hubs are available, but often begin to fail again in as few as 15,000 miles.

Sonnax heavy duty K2 clutch hub 99572-01 features a one-piece design crafted from forged steel that is expertly heat-treated for unbeatable durability.

• Superior one-piece design crafted from forged steel for increased strength
• Unique heat treatment builds in unbeatable durability
• Added oil control lip provides enhanced lube characteristics
