THESE KITS WILL FIT 1994-2003, 7.3 LITER POWERSTROKE DIESELS. A friend needed to replace his Powerstroke exhaust manifolds, so we looked at the application and made sure he had the right hardware for the job. As a result, we know exactly what you need, and we offer them as a kit consisting of eight stainless steel hex head bolts and stainless steel flat washers. The 7.3 is known for its durability and longevity, so it makes sense to use hardware that will not rust instead of the overpriced OEM steel hardware. These are not identical to Ford part# F4TZ-9S425-A, but they are a proven, (and we think, superior) substitute. NOTE: For clarification, these are meant to secure the exhaust manifold to the cylinder head, you will need one kit per manifold.
