A new option for the DDMWorks 4 wheel conversion kit for the Polaris Slingshot. This kit converts any 2015 and newer 3 wheel Slingshot into a 4 wheel vehicle offering you better rear traction, stability, braking and more fun!
This is the self assemble kit version of our best selling 4 wheel conversion kit. It comes with all the pieces needed for you to assemble the kit your self and install it on your Slingshot. This kit does not come with the differential or half shafts, which allows you to select exactly what ratio and parts you want to install. The conversion kit ships from us directly completely powdercoated in your choice of colors and ready for you to assemble and install onto your Slingshot. All the parts except for the differential and half shafts are included in this kit - Main frame, bushings, control arms, brakes, shocks, etc. ready to be assembled and installed. After you assemble the kit and install it on your Slingshot, the grip provided by the extra tire and additional weight is immediately noticeable, giving you much better traction on the rear of the Slingshot, harder launches and more stability when going around turns. The shocks used in the kit are a custom version of the same 3 way adjustable shocks that we offer for the 3 wheel Slingshots and have become a favorite of Slingshot owners. Since you provide the differential with this kit, you have more options available from the 5th generation Chevrolet Camaro with different gear ratios and open or limited slip options available to suit your ride to your exact needs.

We know that as a Polaris Slingshot owner you want your ride to stand out from the rest, so we offer several different options to help you customize your ride to look and perform how you want it.
The first option to decide is the differential ratio you plan on installing in the kit. The stock Polaris Slingshot has a 3.67 final drive ratio, numbers lower than that mean your engine RPM will be lower at a given speed, while numbers higher than that will have higher engine RPM at the same speed. This ratio is a multiplier of engine torque, so the lower the number, the less torque multiplication you will see, which decreases acceleration. However, if you have a lot of power, this decrease will allow the lower gears to become more usable. If you are staying naturally aspirated we recommend staying with the 3.45 ratio or going to the 3.91 for even better acceleration. If you have over 400hp at the wheel now, the 3.27 is a good option along with the 3.45, once again if you have a question on what's best for you, please contact us. There are custom gear ratios available that the differential can be built up with also available on many sources online.
After picking the differential option, next is to pick the colors for the multiple parts of the kit. Here you can go from mild to wild depending on what you want your ride to look like. The base subframe, which bolts to the Slingshot and carries the differential, is typically done a very nice stain black, that looks like it belongs on the Slingshot from Polaris. However if you want to stand out, choose any of the powdercoat options in the drop down menu. The control arms can also be done in your choice of standard colors, Slingshot colors or anything custom you would like. Lastly, the springs for the coilovers are typically silver stock, but we also offer stock Polaris colors or anything you can dream up. If you are not sure what colors would be best, just give us a call, we would be happy to help you design the entire setup to make it perfect for your ride.
After choosing your options, the production of the full kit will start. Once ready, your full 4 wheel conversion ships to you fully powder coated, ready for you to assemble and then install and will include the following -
- Fully welded and powder coated tubular subframe
- Custom Driveshaft with adapter and ABS/traction control fittings
- Welded upper and lower control arms with polyurethane bushings
- Custom DDMWorks 3 way adjustable coilovers with custom spring rates
- CNC machined Billet aluminum uprights
- Custom wheel bearings machined to accept standard Polaris Slingshot wheel bolt pattern
- Brake Calipers with integrated parking brake, brake lines and hardware
- Full Hardware kit for mounting kit to Vehicle
Assembly and installation instructions are included with the kit and are in full color to help you along the way. If you get stuck and need help, our tech line is available most nights and weekends to help you through the installation with phone or text support. You will need another wheel and tire to install on your Slingshot to complete the kit. If you are using another stock Slingshot rear wheel/tire setup, just remember that you will need the tire flipped around for the correct rotation. If you are getting new wheels and tires, just have them mounted up like a regular car with one left and one right. During installation no special tools are needed, although some larger sockets are needed to remove the stock swingarm from the Slingshot.
Whether you are taking it to the track, your favorite twisty roads or just cruising around the 4 wheel conversion kit sets your Slingshot apart from all the rest with a new level in performance, looks and traction that will help you enjoy your ride!
