Installing a new exhaust manifold, or simply removing a stock or aftermarket manifold to change gaskets? If so, you'll find that it is a real hassle to keep the gaskets in place when using standard bolts.
These work on:
89-98 12 Valve Cummins engines using an AFTERMARKET exhaust manifold. They WILL NOT work with the stock manifold, see picture below. (does not have any mounting point/provision for coolant lines)
98.5-02 24 Valve Cummins (works with stock manifold without using spacers or on aftermarket manifolds)
03-07 5.9L Commonrail Cummins (doesn't allow for re-mounting the stock heat shield)
07.5+ 6.7L Commonrail Cummins (doesn't allow for re-mounting the stock heat shield)
We offer two versions, an corrosion resistant alloy steel stud and nut, or a stainless stud and bolt kit.
This kit includes:
x12 Studs (1.959 inches or 49.75 mm) with allen head for easy installation
These studs are not designed to be used with any stock heat shield or exhaust manifold bolt spacers.
Picture depicts a set of stainless studs & nuts and a set of the standard alloy steel corrosion resistant fasteners.
You are only purchasing ONE set of manifold studs, picture simply shows the two styles we offer.
The nuts on the stainless set are SERRATED for better resistance to loosening. We recommend using ANTI-SEIZE on exhaust manifold studs when installing for easier removal.
