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 dealing with 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.

 

In contrast to head bolts, head studs are engineered to not stretch. Xotic Performance head studs are created using premium steel alloys (XOTIC 7200) that are far superior in tensile strength to a bolt. Our head studs are threaded on top to allow for nut placement which will result in a more accurate torque of the head.

 

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.

 

INDESTRUCTIBLE TENSILE STRENGTH

XOTIC 7200 material properties allow for far greater tensile strength compared to 8740 Chromoly steel head studs. Threads are rolled after heat treatment for optimum fatigue strength. Premium quality inspection standards ensure you'll never get a blow head gasket again.

        



OPTIMUM DESIGN

Broached stud ends install & make cylinder head removal easier. Engineered to unleash more performance out of your vehicle. Ample clamping strength prevents cylinder heads from lifting. 

    


ULTRA CLAMPING FORCE

Head studs are designed to retain cylinder seal even with today's extremely high-pressure turbo systems. These studs far exceed clamping forces provided by standard Ford head bolts.

  

 

NUTS & WASHERS INCLUDED

45x Heads Studs, 45x Nuts, 45x Hardened Parallel Washer, 2x Sockets, 2x Allen Wrench, 1x Fastener Assembly Lubricant & Instructions Manual. Black oxide finish protects from wear and tear. Hardened parallel washers allow for uniform load distribution and accurate torque readings.

 

INSTRUCTIONS INCLUDED WITH DRAWN DIAGRAMS

 

All details including torque recommendations are included in the manual for your reference.

    Quality

    Love that they come with the socket needed for the studs. Quality seems to be just as good if not better then arp products.

    Head studs

    Head studs are legit. I like how each end of the threads on the studs are protected in the packaging unlike arp. Reason for the 4 star is the tools that come with it are garbage. Other than that I'd definitely buy again.

    You all can provide a additional set of the 8 mm studs and nuts and washers to help our 6bolt head customers out as you may actually be honest and only add the cost vs inflate cost like arp

    Frequently Asked Questions

     

    Do you have any certificate/tensile strength exam that can attest to the tensile strength you advertise?

    Yes, please click on the following link for a tensile strength report by Atrona Labs. We test our head studs extensively to ensure premium quality standards. The video demonstrated in this short preview highlights the one of many spot inspections performed for our head studs. 

     

    Do these head studs come with paperwork? 

    Detailed instructions are included as part of the kit. 

     

    Does the kit include an assembly lube?

    Yes. Assembly lubricant is included as part of the kit. 

     

    What is the tensile strength?

    220,000-240,000 PSI. 

     

    What material are they made of? 

    XOTIC 7200 head studs are made from premium steel alloys that allow for far greater tensile strength compared to 8740 chromoly steel head studs.

     

    Do these come with instructions/torque sequence for replacing 1 at a time with the heads on?

    This kit includes instructions with torque spec and sequence.
