flex-a-lite has awesome radiators that bolt right up with electric fan packages as well. triple row, aluminum LC engineering has 3 row copper radiators. both are NOT cheap. expect to pay 3-4 bills. but its worth it. stock radiators suck.
Why do stockers suck..? Everyone I've talked to say flex-a-lights suck. With an electric fan, your not gaining enough power (from less rotating weight) to justify the price, ussually less then 1hp gain. With 3-400$ i can think of many other things that can add more power and keep your rig running like a top. But everyone has their own pinion.
