Pusher & puller fans
 

Anyone have advice on fan upgrades ?
Pusher vs puller .... a combination of both etc....

Thanks

aside from quality, how much room you have to work with is usually the deciding factor.

JK has alot of room between the rad and motor so a puller would be best. I guess maybe less chances of it packing with mud too.

Puller fans are generally much more efficient than pusher fans on radiator applications
