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 Polaris 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 multiple colors
  • Larger capacity than the stock tank
  • PLEASE NOTE: IF YOU PURCHASED THE COOLANT REROUTE KIT, THIS WILL NOT WORK ON THE GEN. 2 COOLANT TANK

Went on easy. This is a must for the slingshot or your oem plastic surge tank will fail due to where its located and being close to the engine

Surge Tank
Order arrived very timely. Bottom hose connection a little tricky to connect but manageable. Sight glass is a great feature.
