Part# W8003549


  • Brand New Workhorse Exhaust Manifold Stud & Nut Kit. 8x Studs and Nuts. This kit will only do one side, must purchase a quantity of two if doing both sides.


  • All Workhorse Chassis Equipt with an 8.1L Engine
I have a 2004 Chevy Silverado 2500HD with an 8.1 engine. Will the W8003549 fit the stock truck exhaust manifolds? Ive been looking for a quality set of bolts or studs and there is not much out there for the 8,1s that I can find.

Best regards,
Mike Jones

I have no way to definitely tell you this would work for the pickup variation of the 8.1L but I suspect they would be the same. ( Support )
