I have been looking at purchasing a flex-a-lite fan or one similar for my 05 lly. I have seen them for dodges and fords,but the one for chevy's says not to use as primary cooling. I was hoping to gain the extra ponies by eliminating the oem fan and clutch. Has anyone on here tried one of these set-ups or one made by another company? Whenever I pull, it seems like my fan kicks on ALOT.
