Chevrolet LS/LT to Dodge 8HP70/75/80/90 Automatic Transmission Adapter Kit

KIT OVERVIEW

Performance Adapters — Chevrolet LS/LT to Dodge 8HP Transmission

The ZF 8HP series transmissions are among the best options available for transmission swaps today. Pairing one of these with any LS or LT-based vehicle — whether for street or track use — can completely transform performance and drivability.

This adapter system allows you to mate a GM LS or LT engine to a Dodge V8–platform ZF 8HP transmission, including the 8HP70, 8HP75, 8HP90, and 8HP95 models. These transmissions deliver lightning-fast shifts and are capable of handling substantial power levels, especially when combined with aftermarket transmission control systems.

• Compatible Transmissions: ZF 8HP70 / 8HP75 / 8HP90 / 8HP95 (Dodge/Chrysler V8 applications)
  
• Adapter Plate Material: CNC-machined 6061-T6 billet aluminum for strength and dimensional accuracy
  
• Crankshaft Interface: Includes precision-machined steel flexplate adapter and pilot converter adapter to ensure proper converter engagement and crankshaft alignment
