2003-2007 F250 & F350 6.0L Sinister Diesel 20mm Black Diamond Head Gasket (20mm) SD-BD20-6.0

Much Stronger Than Stock and Can Handle High-Level Tuning

The head gaskets of the 2003 to 2004 F250 and F350 6.0L Powerstrokes were notoriously weak, and would blow out once you threw some performance tuning at your truck. The only real fix was to replace them, and Sinister Diesel's 20mm Black Diamond Head Gasket is a great choice to keep your 6.0L Powerstroke running after you add some extra power and torque. This high-quality head gasket is an all-around improvement over the stock head gaskets, and features a five-layer, stainless-steel design with a durable black polymer coating that can handle increased levels of boost pressure and fueling so that your 6.0L Powerstroke can make excellent levels of power without letting you down.

Strong Design that Drops Into Place of the Stock Head Gasket

The Sinister Diesel 20mm Black Diamond Head Gaskets for the 2003 to 2007 F250 & F350 6.0L Powerstrokes are designed to drop right into place of your stock head gaskets and can be used with your factory head studs or stock-sized aftermarket head studs. The Black Diamond 20mm Head Gasket uses five layers of stainless steel for its core that is then coated in a black adaptive fluoroelastomer coating that allows the gasket to seal tightly to uneven and pitted surfaces much better than stock which keeps cylinder gasses where they should be.

Sold Individually: each of these Black Diamond Head Gaskets are sold separately, and a quantity of two will be required for a complete installation.
