Description

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 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.

Each fastener is hot temperature oiled and brilliant black oxide coated for protection.

The kit contains forged high strength heat treated 12 point nuts and precision ground load distributing washers, ensuring a uniform clamp load, TrueTorq+ ® fastener assembly lubricant and installation procedures.

This kit fits 5.9 and 6.7-liter 24v and Common Rail Cummins engines found in 98.5-present Dodge Ram trucks.

Fastener lengths are engineered from O.E.M. production parts and machine tolerances. Aftermarket or custom manufactured parts may require fitment modifications or length alterations
