Polaris Slingshot Coolant Surge Tank by DDMWorks
The new aluminum coolant surge tank by DDMWorks is a direct replacement of the stock plastic coolant tank on your Polaris Slingshot.  The stock tanks have had a few issues with leaks and brakes, so DDMWorks solves the problem with a larger capacity, solid built tank.  The Slingshot coolant tank also has an integrated sight glass to allow the levels to be checked without removing the cap.  Don't forget to get the DDMWorks Silicone Hose Kit as now is the perfect opportunity to swap your stock hoses out.

Benefits of the DDMWorks Coolant Surge Tank for the Slingshot

  • Stronger than the brittle plastic tank, allowing for higher engine bay temperatures
  • Integrated sight glass allows you to check coolant without removing the pressure cap
  • Available in black or red
  • Larger capacity than the stock tank

Nice replacement for the stock plastic tank
I ordered this in red to replace the stock plastic tank. I wasn't comfortable with the plastic tabs on the stock tank. The install wasn't too bad. The bottom clamp was a bit troublesome to tighten, but not a big deal. All in all, I am happy with the new tank, and it matches my red manifold nicely. I would recommend it as a great improvement over the stock one.

Better than OEM
Fantastic part that is a much higher quality than the plastic oem tank that broke and leaked coolant everywhere while driving.

Coolant tank
Awesome product and durable. I don’t think I will ever have to change it again. At least I hope not because it is definitely a tight fit but well worth the little hassle. Even if you don’t need it right now I promise you you will. Get it while it’s in stock.
