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

DDMworks Aluminum Surge Tank
Purchased this Coolant Tank because none available thru Polaris and could not wait . Please be careful when ordering because mine came with no fittings on the tank ? Only threaded holes . Slingmod told me to take the fittings off of the OEM tank and transfer them ? Really !! . Big disappointment and then running around trying to find fittings !!!

Saved the day!
Well made, saved my Summer. My LFX Miata uses a Polaris Slingshot coolant bottle and After going through two that crack over time I found this most excellent product. Looks way better in my engine bay than the original.

Surge Tank
Was easy to install. My only concern was it comes with a 6 PSI cap and my old stock cap was 15 PSI, but it didn't seem to make a difference in the operating temp.
