ATI aluminum TH400 SuperCases feature SFI certification and a bellhousing. Developed to eliminate all weak points found in the original TH400 case, the rugged SuperCases and bellhousings are SFI-approved for competition. In addition, the SuperCases have a removable bellhousing that bolts directly to the case instead of using the pump bolt locations. They have been engineered to accept all internal TH400 components.
