Tired of constantly filling your 6.4 Powerstroke radiator with coolant because you have a leak? The engineers at Mishimoto have been hard at work designing an all-aluminum 6.4 radiator and upper support bar bundle to put an end to puddles of coolant under your truck. The Mishimoto 6.4 Powerstroke radiator is constructed from high-quality, aircraft-grade aluminum with a 100-percent brazed aluminum core. The core is then TIG-welded to aluminum end tanks for superior durability and longevity. Couple that radiator with our upper support bar, and you have a recipe for a dry shop floor. Engineered right here in Delaware, our upper support bar is constructed of heavy-duty steel and firmly secures to your truck with cast-steel anchor points. All of that steel minimizes front end flex, improving the truck?s rigidity, and saving your radiator. Of course, both the 6.4L upper support bar and radiator are backed by the Mishimoto Lifetime Warranty;so you'll never have to worry about leaks again!
