Jeep JK Hemi Conversions in Sonoma County

For Jeep Wrangler JK owners who want V8 power, West Coast Hot Rods  Inc. performs Hemi engine conversions for 2007–2018 models. We help plan the conversion, integrate the engine with the supporting drivetrain systems and build a setup suited to how the Jeep will be driven, from regular street use to off-road travel.

Is a Hemi Conversion Right for Your Jeep JK?

A Hemi conversion can provide the additional horsepower and torque some Jeep JK owners want for larger tires, modified drivetrains, off-road use or stronger highway performance. But an engine swap should be planned around the entire vehicle, not treated as a stand-alone engine installation.

​

West Coast Hot Rods Inc looks at the Jeep, its current modifications and how the owner plans to use it before recommending the direction of the conversion. If you already have an engine or parts, we can evaluate what you have and determine what may be usable.

More Than Installing an Engine

A successful Hemi conversion requires the engine, transmission, drivetrain, electrical systems and other related components to work together properly. West Coast Hot Rods Inc. handles  the conversion as a complete system and can also troubleshoot problems with conversions or components that were installed incorrectly.

​

​The exact work depends on the Jeep, the engine and drivetrain being used, existing modifications and the intended use of the vehicle.

Hemi conversion work may include:

 

  • Planning the engine and drivetrain combination

  • Hemi engine installation and integration

  • Transmission and drivetrain work

  • Electrical integration and troubleshooting

  • Diagnosing improperly installed components

  • Related axle, gearing and suspension work

  • Finishing a conversion started by the owner or another shop

Start With a Project Consultation

Every Hemi conversion is different, so an accurate estimate requires more than a brief phone description. We will need to understand the Jeep’s condition, current drivetrain, existing modifications, available parts and what you want the completed vehicle to do.

 

West Coast Hot Rods Inc. can help determine whether the conversion is practical, identify the supporting work it may require and develop a plan before the build begins.
