Have ever run a Flex-a-Lite Dmax kit or towed heavy with a Dmax?
The F/L does not keep up with the stocker, nor is it engineered that well, as it nearly set my truck on fire from melting their inadequate fuse block. They eventually fixed the fire hazard, but they are still far weaker than the stock fan.
I've run both ways, and I can tell you for a fact the F/L is not suitable for heavy use. Nor did it improve my ET's, since the factory fan is not engaged while going down the dragstrip.
Basically, do not buy a Flex-a-Lite. Not a good mod for our trucks. Maybe for racing to cool the engine between passes, but not for towing.
