DHD 800-039 TORQ Series 8740 Chromoly Duramax Main Studs LBZ LMM LML L5P

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 the hobbyist 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 attributes to that of  ARP2000 material.  Aside from excellent tensile strength, our threads are rolled after heat treat which provides a much high quality thread and minimizes thread fatigue. Each stud is designed to match the length, size, weight and threads that will best benefit your application.

Converting your Duramax over to main studs will greatly increase the rigidity of your block and stabilize your main caps. DHD always recommends transitioning to studs when billet mains are used. (Note: The increased torque applied to the main cap will cause cap distortion. Main bore should be finish honed with studs installed and torqued to spec.)
