INDESTRUCTIBLE TENSILE STRENGTH
Rated at 220,000 psi tensile strength. Threads are rolled after heat treatment for optimum fatigue strength. Premium quality inspection standards ensure you'll never get blown head gaskets again.
OPTIMUM DESIGN
Broached stud ends install & make cylinder head removal easier. Installation manual is included with drawn diagrams to ease the installation process.
ULTRA CLAMPING FORCE
Head studs are designed to retain cylinder seal even with today's extreme high pressure turbo systems. These head studs far exceed clamping forces provided by standard Ford head bolts.
NUTS & WASHERS INCLUDED
Hardened parallel washers allow for uniform load distribution and accurate torque readings.
Head studs vs Head Bolts
In every diesel car, there are high cylinder pressures that can damage head gaskets. Factory OEM head bolts are torque to yield, meaning you torque the bolt to a specific torque with a final 90 degree rotation that will place the bolt at its’ maximum stretch point.
Our observation through years of inspecting and repairing diesel trucks is that when you add parts that increase horsepower (turbocharger, injectors, chips etc.), you risk creating higher cylinder pressures lower than your RPM range, consequently leading to a blown head gasket.
Rather than blowing your head gasket again, we highly recommend replacing your head gaskets with fasteners that have a proven track record of not stretching - so that you never have to deal with the exhaustive procedure of replacing another failed head gasket.
Installation Instructions Included with Drawn Diagrams
- Use a thread sealer to lubricate block threads of the head studs (only applies if the cylinder head studs extend into the water jacket).
- Screw studs as tight as can be made finger tight (no tool necessary), and install cylinder head.
- Using THE FASTENER ASSEMBLY LUBRICANT included in the package, lubricate the head studs (ensure nuts and washers are lubricated as well).
- Install the lubricated nuts and washer onto the head stud as tight as can be made finger tight (no tool necessary).
- Using the torque recommendations in the manual, tighten the cylinder head bolts in 3 equal steps.
