OptiTorque Patriot Head Stud Kit for 12 Valve

100% manufactured with pride in the USA.

Produced from American melted aircraft quality fine grain clean steel, each fastener is “batch” heat treated with every part individually loaded and arranged to produce the most uniform hardness available ensuring an even clamp load.

All fasteners are stress relieved prior to centerless grounding for maximum straightness and exact tolerance.

The Patriot Series fasteners are thread rolled hard and include an optimised stretch area designed to out perform the competition in cycle fatigue.

Each fastener is hot temperature oiled and brilliant black oxide coated for added corrosion resistance.

The kit contains: forged high strength heat treated 12 point nuts and precision ground, thru hard load distributing washers to further promote a proper and uniform clamp load, (6) high strength m8x1.25 Rocker pedestal attaching bolts, TrueTorq+ ® fastener assembly lubricant and installation instructions.

This kit fits 12v Cummins engines found in 89-98 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**
