Performance Heavy Duty Valve Spring Set for 03-07 Ford 6.0 Powerstroke
If you have increased the horsepower and boost on your 6.0 Powerstroke, you should consider installing a set of these heavy duty valve springs. The stock valve springs can float under high rpm, high boost, and increased horsepower applications. When the valves float, not only is there a potential for piston to valve contact, but the lifters slam the camshaft causing premature lifter failure. By installing a set of these heavy duty valve springs, you will insure that the valve opens and closes as it suppose to not only keep your engine safe, but also to provide the maximum horsepower and torque.
