Evolution Fan Shroud Velocity Ring

If you like the Evolution fan shroud, you'll like it even more with this new velocity ring, specifically designed for the Evolution fan shroud.
 
Increase, the already impressive airflow of the Evolution fan shroud, by another 7+%!
 
The Evolution fan shroud, with an OEM doghouse fan will flow a whopping 51+% airflow on it's own, and now with the new velocity ring you can push that all the way to 59+%!
 
All Evolution fan shrouds ordered after November 17, 2024 will include the provision for mounting the velocity ring, so it's a simple bolt-on installation.  No need for welding or riveting, or rivet nut installation.
 
If you have an older Evolution fan shroud, you can select to order a template to modify the fan shroud, installing four rivet nuts in the locations marked by the template.
