Universal Tuck Radiators

Exclusive Collaboration With

We can remember like it was yesterday, Ryan Basseri, owner of Rywire.com, walked into the CSF booth at SEMA 2014, CSF’s 5th SEMA show as an exhibitor. Ryan started to his explain the “tuck” radiators he was having made by another radiator manufacturer. He desired more from his current supplier. He wanted something better and more advanced than the generic radiator core and home made fabricator looking unit that’s all too common in the industry today. He was looking to separate his product from the rest of the crowd. Everyone else was generally making the same thing, everyone copying the same thing as everyone else…

A wiring and motorsports electronic genius, Ryan’s mind started to flow with CSF’s world leading manufacturing capabilities. Rywire came up with a universal threaded inlet/outlet bung system that could use more “high-end” advanced -16 AN fittings, 1.25″ OEM style slip-on hose connections, or even be plugged, for multiple installation configurations. Combined with CSF’s 1-hour mirror polish finish, CNC machined brackets, fan shroud, option for dual-fans, and best-in-class packaging, there was finally a major leap in innovation for the tuck radiator market.

The rest continue to chase, trying to mimic the winning combo of CSF + Rywire… however; no one comes even close.
