Q: The Video shows the chassis with a radiator and running but the photos don't. What will I be getting?

A: The Video shows more of what a customer will receive with minor difference. We are constantly improving our designs, refining out manufacturing capabilities and getting new better venders so there will be some subtle changes but the running turnkey version you see in the video is what you should expect

Q: What else do I need to supply?

A: Wheels and tires for shipping and any additional components you need us to install for you to feel comfortable.

Q: Can I have a different motor and transmission combination?

A: Absolutely, contact us with your needs and we’ll work to get it taken care of but the price will need to be adjusted for any variables. Obviously super chargers need a different pulley belt system and turbo would need a different exhaust system just as an example.
