The Project 324 kit makes it easy to convert your Slingshot from 3 to 4 wheels.


  About the Project   

Project 324 was developed to make it easy to add a fourth tire to your Slingshot to improve performance, handling and safety.
  • Launch harder off the line with two wheels putting down the power (especially important in boosted applications)

  • Stop shorter with four brakes and more rubber touching the ground

  • Experience less body roll with two tires carrying the rear of the vehicle

  • Corner with confidence with more rear grip



  How it Works   

Project 324 Kit + Your Slingshot

The Project 324 kit is a DIY 3 to 4 wheel conversion kit for your Slingshot. This means you can assemble and install the kit yourself.

But don't worry! We've done all of the fabrication and other hard work for you so assembling and installing the kit is very simple.

** Installers are also available. Please contact your nearest dealer to ask about having the kit installed. **
