Pusher Fan Clearance
Been running my 17" S blade puller right up against the radiator core for 4 years now. :D
It's on foam pads and not plastic to fins contact.
I'm with TrailBeast. I installed a 16" SPAL (#301022047 - which outperforms Derale, IMO) and had to modify the latch support for motor clearance. The SPAL moves some serious air and you need to space any fan away from the radiator core slightly for it to work properly. Mine's spaced about 1/2".
