LOJ Conversions LS / LT to Hemi 8HP / ZF8 Transmission Adapter Package - SFI Approved
MADE IN THE USA & Fully SFI Certified! The LOJ Adapter Kit includes a full replacement flexplate/flywheel rather than relying on an inline adapter between your OEM GM flexplate and 8HP Converter. This provides a simpler solution that has fewer failure points and a more straightforward design.
The LOJ Conversions Gen III/IV Small Block Chevy (LS Engines) and Gen V Small Block Chevy (LT Engines) to Hemi 8HP / ZF8 (8HP70, 8HP75, 8HP90, 8HP95) Transmission Adapter specifically designed for adapting the increasingly popular ZF 8-Speed transmissions to your favorite LS and LT engines. The straight-forward approach and overall simple design will allow a seamless integration of these LS engines with the Hemi Truck and Car versions of the ZF8. The adapter plate design incorporates a 360* mounting surface and mounts to GM factory style cast oil pans for enhanced rigidity.
The included billet aluminum Flexplate is a complete replacement of the factory LS/LT 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 is press fit into the stock pilot bearing register on the crankshaft to prevent unwanted noise from slip-fit parts and to properly align the converter to the crankshaft.
UPDATE: New Design works with BOTH Converter Pilot Diameters! Not sure what you have? Doesn't matter anymore.
