What drivers say about XOTIC PERFORMANCE™
Exhaust Manifold Stud Kit - 1994–2018 5.9L & 6.7L Dodge Cummins
Upgrade your Cummins exhaust manifold hardware with a complete stud-based fastener solution engineered for durability, proper fitment, and long-lasting performance. This kit replaces worn factory bolts and provides the correct hardware required when installing factory or aftermarket exhaust manifolds.
Using manifold studs helps improve alignment during installation and promotes more consistent clamping force compared to traditional bolts—especially important in high-heat diesel applications subject to thermal expansion and vibration. For best results, new exhaust manifold gaskets should be installed prior to securing the manifold.
