Upgrade the rusty or broken exhaust manifold bolts on your Cummins 5.9L/6.7L with the PPE Exhaust Manifold Bolt and Spacer 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 Bolt is centerless ground and rolled with extreme precision, reducing stress concentrations, and increasing durability. The use of Spacers mitigates the heat expansion on the Bolts and prevents permanent yields. All fasteners have a black oxide finish.
