Review on 💪 Enhance Performance with 6.0 Blue Spring Kit Upgrade for Ford Trucks - F250, F350, F450, F550 2003-2007 - Replace 3C3Z-9T517-AG by Jake Larson

I installed this in my 2006 6.0 PowerStroke and it almost caused an overclocking situation! With this "upgrade" I was over 90psi and fuel was being expelled through the seals into my crankcase, diluting my engine oil with diesel. Have been driving the truck for about 1.5 weeks and my oil has already accumulated 7 GALLONS OF DIESEL FUEL. Could have wrecked the engine but (fortunately) wouldn't start and took it to my mechanic. Don't buy that crappy quality spring, spend a few bucks more on a Ford and sleep tight knowing you won't ruin your truck!
