Order the OptiTorque Technologies 10286 TorqueMaster Head Stud Kit from XDP for your GM 6.6L Diesel today. OptiTorque takes pride in offering a range of material grades to cater to various applications, ensuring every customer finds their ideal solution. Crafted with precision, these studs are meticulously crafted using domestically sourced premium steels. The oversized steel bars undergo a rigorous cold-working process, enhancing their mechanical properties and eliminating any surface imperfections.

What sets these fasteners apart is their exclusive heat treatment method, distinct from those used in the automotive, commercial, and aerospace industries. This proprietary process empowers each fastener to achieve higher tensile strengths while maintaining exceptional toughness. To guarantee proper performance, the fasteners are subjected to centerless grinding, ensuring perfect concentricity and eliminating any surface flaws resulting from the heat treatment process.

The threads on these fasteners are roll-formed in the hardened state, adding to their durability and reliability. After threading, the fasteners undergo stress relief, meticulous deburring, and are then plated or polished, all tailored to meet the specific packaging requirements of each customer. Don't wait--upgrade your GM 6.6L Diesel with the OptiTorque Technologies 10286 TorqueMaster Head Stud Kit from XDP today.
