This is our Dodge and Chrysler 2.2 and 2.5 copper coated exhaust and intake manifold nut and polished hex allen head stud upgrade. These are the highest quality GRADE 10 manifold stud nuts and studs that are direct replacements for the factory grade 8 steel nuts and studs. The nuts are actually manufactured for the high performance turbo Porsche automobile and the studs are cold finished and polished studs that are harder and have a higher tensile strength than standard studs and are a perfect standard fit for our turbo Dodge automobiles.
Unlike the standard grade 8 studs and nuts for the non-turbo car, these are Porsche GRADE 10 steel nuts with the legendary Porsche style copper cladding for added serviceability, durability, and strength. These are not the less expensive grade 8 steel nuts. And our studs are grade 10 rolled steel studs with a hex alen head. These studs are far above the quality and strength of the factory cut thread studs.
These 8mm x 1.25 GRADE 10 steel nuts and studs install directly on the factory exhaust or intake manifold without any modifications necessary and since they are both self locking and copper clad, they will not loosen nor bond to the steel studs. So you get not only added grade 10 strength, you also get extended reliability and serviceability due to the self locking features and copper clad technology. They are also the standard 10mm hex wrench size so they are installed or removed using the same tooling as the factory nuts.
By replacing the factory grade 8 steel nuts and studs with these GRADE 10 copper coated manifold flange nuts you get the following advantages:
- Increased fastener strength, grade 10 Vs. grade 8
- The fastener will not bond/rust to the stud making future removal easier
- You will gain 50 HP and 75 ft/lbs of torque (just kidding!)
