I already installed the studs and seem to hold up well. Honestly i would prefer running these studs any day for how much cheaper then other brands they are and work the same.

Very straight forward installation instructions and a breeze to install. Just time consuming.

Super nice so far no problem definitely we’ll recommend it great deal for the price.

Shipping was quick easy installation with directions included.

2008 6.7 Cummins. Checked valve lash before and after and it pressed the head down about .002 in. So they are stronger than stock head bolts. I think these are worth it if you just have factory turbo with tunes.
