Don't be fooled by late arrivals to the head stud market! Our Torq series studs have set the benchmark for quality and performance for over 3 years! DHD's TORQ series studs provide the perfect blend of quality and value that all Motorsports enthusiast's seek. These studs are designed to provide marketplace options for street trucks under 800HP and a high quality budget friendly alternative to inadequate OE hardware. 

While working directly with the manufacture we have developed a 220,000psi capable 8740 chromoly stud with similar alloy attributes to that of  ARP2000 material.  Aside from excellent tensile strength, our threads are rolled after heat treat which provides a much higher quality thread and minimizes thread fatigue. Each stud is designed to match the length, size, weight and threads that will best benefit your application. Studs come with a broached allen head for easy and accurate height install.

Converting your Duramax over to head studs will greatly increase the clamping load on your head gaskets. Thus keeping coolant contained and all that valueable boost right where you want it! We have consistently stressed these studs to boost levels higher then 45psi without failure. Buy TORQ, the first and the original ARP 2000 alternative!
