The factory exhaust manifold hardware Cummins used 20 years ago was designed extra-long with spacers to accommodate for expansion and contraction through heat cycles.  Once you replace your old rusty and crusty manifold, it’s hard to reinstall the grody factory hardware and spacers, so you instead move to shorter hardware, which reduces the fasteners' ability to cope with heat cycles.

We at Power Driven decided to fix this problem by releasing our own factory hardware, but in stainless steel!  So now you have the same great hardware retention that Cummins deemed necessary back in 1989, but in a superior material that will continue to look killer for years to come!

Kit comes with:

• 12 X Stainless Long Manifold Bolts
• 12 X Stainless Machined Spacers
• 2 X Stainless Short Hardware
  

Installation Notes:

Due to the voluptuous nature of some aftermarket manifolds, we also supply two shorter bolts that will fit into most aftermarket manifolds that don’t allow a spacer to fit.  Manifolds like 2G location steed speeds are designed to allow all factory-style hardware to be used.
