PACH304: Chevrolet LS/SBC/BOPC to Dodge 8HP70/75/80/90 Automatic Transmission Adapter Kit

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

KIT OVERVIEW

Performance Adapters — Chevrolet LS/LT to 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.

Technical Overview

• Compatible Engines: GM Gen I, II, III, IV, and V LS/LT-based engines (4.8L–6.6L) With 6 Bolt Crank
  
• 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
  
• Torque Capacity: Supports power levels exceeding 1000+ HP when used with upgraded 8HP internals and aftermarket control systems
  
• Transmission Control: Compatible with popular standalone controllers such as HTG Tuning GCU, Turbo Lamik, and Sound German Automotive (SGA) systems & More
  
• Starter Compatibility: GM High Torque Mini Starter Bolted into the Adapter plate in factory location area
  
• Input Shaft Alignment: Engineered concentricity within ±0.002” to maintain clutch pack and input shaft longevity

Performance Benefits

• Ultra-fast shifts (as low as 200 milliseconds) with adaptive shift logic
• Reduced parasitic loss compared to traditional automatics
• Eight optimized gear ratios for both drag and road course performance
• Enhanced fuel efficiency at cruising speeds
• Future-proof control options, supporting paddle shifters and sequential operation modes

Applications

Ideal for street performance builds, pro-touring projects, modern resto-mods, and drag or track vehicles where maximum acceleration, shift precision, and reliability are desired.
