New Product Launch – Turbo 400 Steel Direct Drum

When horsepower climbs and abuse becomes part of the game, the factory cast direct drums and lightweight aluminum drums become a known weak point in both Turbo 400 and 4L80E transmissions. Hard launches, aggressive shifts, heavy drag & drive setups, and high RPM operation can push those components past their limit — often with catastrophic results.

Independence Driveline is proud to introduce our new Turbo 400 Steel Direct Drum, engineered for builders and race shops demanding strength, durability, and reliability in serious performance applications.

Available Options:
• 34 Element Sprag Version
• 36 Element Sprag Version

Our 36 Element package is offered as a complete performance kit featuring:
• CNC Machined Pressure Plate
• Performance 5 Clutch / 5 Steel Clutch Pack
• Heavy-Duty Steel Direct Drum Assembly

Designed for both Turbo 400 and 4L80E transmissions, these drums are built to handle the punishment that high horsepower street, strip, and drag & drive vehicles deliver.

Whether you’re upgrading a proven race combination or building a transmission for today’s power levels, Independence Driveline components are built to keep you moving forward.

Unleash the Power of Independence.
