OptiTorque 2011+ 6.7L Cummins Torquemaster Head Studs

If your vehicle is 2010 or newer, it is best to measure the depth of your block’s bolt holes. If they all measure the same depth, then these are the studs you need.  If they are not, then you need the two-length stud 10272. 100% manufactured with pride in the USA. Crafted from vacuum melted micro alloyed American manufactured HSLA steel, each fastener is heat treated and undergoes a proprietary tempering process to achieve a fine grain structure prior to thread rolling. The coarse threaded (block) end of the fastener features a bottoming boss eliminating the purchase of special tools to “hold” the fastener during installation. These fasteners have 15% MORE clamp load than an ARP 2000. These premium fasteners use ALL available factory block threads to distribute stress loads and are fully stress relieved prior to centerless grounding for maximum straightness. The Torque Master Series fasteners feature the greatest stretch area in their price class optimizing cycle fatigue properties.
