But don't worry! We've done all of the fabrication and other hardwork for you so installing the kit is very simple.
** Regional installers will be available soon. If you are interested in having the kit installed for you, please contact us directly. **
The Project 324 kit includes all of the pieces you need except the extra rear tire and wheel. You'll need to purchase the 4th tire and wheel yourself.

Any 2015 to 2019 Slingshot is compatible with the Project 324 kit. More info »
The swing arm mount changed for the 2017 models so we have to send slightly different pieces for the 2015-2016 Slingshots. Make sure you select the correct year model when submitting your order.
The only other major purchase you will need to make is the fourth wheel and tire. More info »
You will have to buy another rear tire and wheel for your conversion. Make sure the specs for the tire and wheel you purchase match the specs of your original rear tire.
Other than the tire and wheel, you'll also want to buy brake fluid to top off the reservoir when you bleed the brakes. You will also need gear oil for the differential.
You will need a jack, jackstands and a set of ramps. The kit will come with the rest of the tools you need. More info »
You'll use a jack and jackstands to hold up the rear of your Slingshot and ramps for the front. The kit will include the rest of the tools to assemble and install your Project 324 kit.
Other than trimming two of the rear plastic covers, the conversion is completely reversable. More info »
If you hold on to your original driveshaft, angle drive, swing arm and other stock pieces you can revert back to three wheels. Two plastic pieces have to be trimmed so those will have to be replaced if you want it to look completely stock.
