H11 Ultimate Duty Head Studs
Every JE Pro Seal Head gasket utilizes the best raw materials available such as AISI 304 Stainless Steel. State of the art processes such as in-line laser cutting and multi-stage embossing technologies are utilized to ensure the highest level of quality available. In addition, every layer of our Multi-Layered Steel gaskets is invididually cut and formed to optimize performance.
Proprietary Coating Technologies: Multiple layers are used to provide the ultimate seal between the head and block mating surfaces. These coatings will normally eliminate the need for additional deck surfacing. Our coating processing provides 100% encapsulation of all exposed metal, far superior to other products that leave exposed raw steel on the edges. The layers include fluoroelastomer (FKM) for extreme temperature and chemical resistance. This technology provides superior conformability, oxidation resistance, and better removal, even after extreme temperature exposure.
If you're looking to make big power (proven over 1000+whp) but don't like the idea of lifting your cylinder head and replacing head gaskets frequently these are exactly what you need! These studs are manufactured specifically for us by A1 Technologies and utilize an H11 material that is much stronger than the typical 8740 chromoly and yields a tensile strength of 260,000 psi. They are also provisioned with a hex broach on the top of the stud enabling you to install them with the cylinder head on the car if necessary.
The dog point feature seats the stud in the block and preloads the fastener for an accurate and repeatable torque sequence. We also include the new ARP Ultra Torque assembly lubricant with each set. When it comes to head stud performance properly torquing the studs is paramount and we have made every effort to ensure torque precision and repeatability!
