Required space for radiator plus high profile USA made SPAL fan is 6.5 inch.<br><br>Bracket mounted fans is our simplest configuration for an electric fan set up. As the name implies, this set up uses simple brackets to mount a fan against the radiator core.<br> <br>Pros: This package is very thin and will fit in many applications where available space is limited on the engine side of the radiator for a "puller fan" set up. Also, bracket mounted fans are the only viable option for grill side "pusher" fan set ups, that allow air flow.<br><br> <br>Cons: Because the fans are only mounted on a bracket and no shrouding is applied, the fans will only create air flow on the radiator core surface area directly in front of the fan when in use and will not utilize the complete radiator core.
