Upgrade the rusty or broken exhaust manifold bolts on your Cummins 5.9L/6.7L with the PPE Exhaust Manifold Stud, Nut and Washer Kit. Over time, repetitive heat cycles can take a toll on factory bolts, causing fatigue and stretching, ultimately resulting in troublesome exhaust leaks.

Each PPE Manifold Stud is centerless ground and rolled with extreme precision, reducing stress concentrations, and increasing durability. The use of studs and nuts allows for precise torque reading and more even load distribution. This kit comes with 12-point flange nuts. All fasteners have a black oxide finish.
