Complete T-56 Magnum package for Gen 3 Hemi, Hellcat, and Hellephant engines up to 1,200 HP with a driver-side starter. Includes bellhousing, RAM Force twin-disc clutch, hydraulics, wiring harness, yoke, mount, fluid, and starter.

This is the ultimate T-56 Magnum package for high-power Gen 3 Hemi, Hellcat, and Hellephant engine builds. Engineered to handle up to 1,200 HP, this kit is configured specifically for engines using a driver-side starter. Every component is selected for durability, perfect mechanical alignment, and the ability to withstand high torque and aggressive driving.

This system is not vehicle-specific and works with any modern Gen 3 Hemi family engine. If your headers require a passenger-side starter, see our alternate Bowler package.

If you need vehicle-specific parts—crossmembers, hydraulics, offsets—contact our team and we’ll help finalize your setup.
