Eliminate Troublesome Exhaust Leaks with PPE

Over time, the factory exhaust manifold bolts on your 1998.5-2018 Ram 5.9L or 6.7L Cummins can weaken due to constant heat cycles and vibrations. As the metal expands and contracts, stock bolts can stretch, loosen, or even break, leading to exhaust leaks that rob your engine of performance and efficiency. If you've noticed a ticking sound from your manifold or suspect a leak, replacing those worn-out bolts is a smart move. The PPE Exhaust Manifold Stud, Nut & Washer Kit is designed to eliminate these issues by providing a much stronger and longer-lasting solution. This kit replaces the factory bolts with high-strength chromoly alloy steel studs, which are far more resistant to stretching and fatigue. With a tensile strength of 180,000 PSI, these studs are built to handle extreme heat and pressure without losing their clamping force. Unlike standard bolts, which rely on threads cut directly into the manifold, these studs use a more secure fastening method with included 12-point flange nuts. This allows for more precise torque readings and even load distribution, helping to create a better seal between the manifold and the cylinder head.

High-Quality Construction with Straightforward Installation

Every fastener in this kit is finished with black oxide coating to protect against rust and corrosion, ensuring long-term reliability even in harsh conditions. PPE also includes a packet of thread lubricant, making installation easier and helping prevent galling when tightening down the studs and nuts. Whether you're replacing broken bolts, upgrading to a performance manifold, or simply looking to prevent future leaks, this kit is a worthwhile investment for any Cummins owner. Installation is straightforward and can be done with basic hand tools, though some manifolds may require heat or penetrating oil to remove old bolts. If you frequently tow heavy loads, run higher boost pressures, or just want to avoid the headaches of future exhaust leaks, upgrading to the PPE Exhaust Manifold Stud, Nut & Washer Kit is a simple and effective way to keep your engine running at its best.
