The Project 324 kit is a DIY 3 to 4 wheel conversion kit for your Slingshot. This means you will install the kit yourself.
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.
When ordering the kit you can decide if you want the kit fully assembled or in pieces.

The best way to order your Project 324 kit is here on the website using the product order buttons below. You will be able to select the kit you want and provide us with the information we need to produce your kit.
The only payment due today is the deposit for the kit. You will pay the remainder before your kit ships.
The Basic Kit is shipped uncoated. You will need to paint or have the parts powder coated yourself. Alternatively you can choose the powder coat option when you place your order.
The Bolt-On Kit will be powder coated and assembled before it is shipped. The default color is gloss black.
If you want your kit coated with a custom color, you will need to email us the color code from Prismatic Powders. Custom colors cost $100 more than the default gloss black.
The shipping price is not included in the kit price. It will vary depending on the options selected and your location.
We will work to find the lowest shipping price via UPS or YRC Freight. The fully assembled Bolt-On Kits will need to be shipped by freight due to the oversized dimensions. The unassembled Basic Kits can be shipped via UPS because the parts can be broken up into smaller packages.
Current shipping time is 6-8 weeks.
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.
