Billet 7075 Aluminum D Drum — BMW ZF 8HP7X (8HP70/75/76)

AME Motorsport Billet 7075 D Drum — a CNC-machined upgrade for the ZF 8HP7X automatic transmission. Machined from a solid billet of aerospace-grade 7075-T6 aluminum, it replaces the factory D-clutch drum, a well-known weak point in high-power built 8HP transmissions. Why upgrade your D Drum? As BMW and other ZF 8HP-equipped platforms are pushed well beyond stock power, the factory D drum becomes a common failure point under high torque and RPM. Our billet 7075 replacement is engineered to take the load — stronger and lighter than the factory component — so your build can hold the power with confidence.
