Pre-Order! Adapters will ship March 2026.
The LOJ Conversions Gen III/IV Nissan VK56 Engine to Hemi 8HP / ZF8 (8HP70, 8HP75, 8HP90, 8HP95) Transmission Adapter specifically designed for mating to sought after ZF 8-Speed transmissions to your favorite Nissan V8 Engine! The straight-forward approach and overall simple design will allow a seamless integration of the VK56 Truck engines with the Hemi Truck and Car versions of the ZF8. The adapter plate design incorporates a 360* mounting surface and mounts to the VK56DE and VK56VD engines and oil pans.
The included billet aluminum Flexplate is a complete replacement of the factory VK56 Flexplate. Don't waste your time with torque converter adapters that still rely on the weak stock Flexplate. Upgrade to a fully billet CNC machined Flexplate from the start for maximum power holding and durability.
The steel converter pilot adapter functions as a torque plate for the flexplate and has an inset to allow compatibility with both 46mm and 34mm 8HP converter pilot diameters.
