KIT OVERVIEW

K-Series to Chevy V8 Transmission Adapter Kit

Bring modern Honda performance together with proven GM drivetrain strength. This adapter kit allows you to bolt a Chevy V8 transmission directly to a Honda K-series engine, creating a versatile solution for high-performance swaps, drag builds, drift cars, and custom projects.

The kit is designed around the classic Small Block Chevy crankshaft bolt pattern, giving builders the flexibility to run either an automatic or manual transmission using widely available GM components. By utilizing common GM drivetrain parts, this setup keeps replacement components easy to source and affordable.

Our precision-machined adapter plate is constructed from 5/8-inch-thick material to provide excellent strength and durability while maintaining proper drivetrain alignment. The design also incorporates a GM high-torque mini starter that mounts directly to the adapter plate, allowing the use of a full-size GM flexplate or flywheel.

To complete the setup, builders will need to source a 14.13-inch, 168-tooth flexplate or flywheel depending on the transmission being used.

This kit opens the door for pairing the high-revving Honda K-series platform with some of the most proven and durable GM transmissions on the market.
