Over time, factory bolts can corrode or break due to heat exposure, causing annoying exhaust leaks. But with this kit, you can easily upgrade those worn - out bolts. Each PPE Manifold Stud is precisely centerless ground and rolled, which reduces stress concentrations and boosts durability. Using studs and nuts enables accurate torque measurement and even load distribution. The set comes with 12 - point flange nuts, and all fasteners have a black oxide finish. Part Number: 318034300. Features: Made of Chromoly alloy steel with 180,000 PSI tensile strength. It has a black oxide finish and includes a thread lubricant packet.

Using this exhaust manifold bolt and spacer set is quite straightforward. First, make sure your vehicle engine is cool. Then, remove the old and corroded bolts from the exhaust manifold. You may need to use appropriate tools for this. If you have a 2003 - 2007 5.9L Cummins, remember to take off the factory heat shield. For 1994 - 1998 5.9L engines, this set only works with aftermarket manifolds. After removing the old bolts, clean the areas where the new bolts will be installed. Apply the included thread lubricant to the new bolts. Install the 12 flange head exhaust bolts and spacers, followed by the 2 stainless - steel socket bolts and washers. Use a torque wrench to ensure the bolts are tightened to the correct torque for accurate and balanced installation. As for maintenance, periodically check the bolts for any signs of looseness or corrosion. If you notice any issues, retighten the bolts or replace them if necessary. Keep your engine and the exhaust system clean to prevent excessive dirt and debris from affecting the performance of the bolts.
