Sonnax highlights the heavy duty “E” clutch hub (#35572-38T) for ZF8HP70 transmissions. This clutch hub is crafted from forged 4000-series aluminum, the same material used for high-performance engine pistons.
According to Sonnax, the improved material significantly increases “E” clutch durability. Users can restore normal operation to ZF8HP70 transmissions after “E” clutch hub failure and avoid comebacks, the company adds.
