Mishimoto Exhaust Manifold Stud Kit - Ram Cummins 5.9L/6.7L 1994-2018

Mishimoto exhaust manifold stud kit for the 1994-2018 Dodge/Ram 2500/3500 5.9L and 6.7L Cummins diesel. The chromium-infused steel studs increase clamping force between the manifold and cylinder head to cut boost-killing leaks and reduce manifold warpage, while 12-point hardware resists rounding and makes lining up a heavy manifold and turbo far easier. Backed by a lifetime warranty.
