Purchased from: Norcal Diesel Performance

Bought head studs about 2 months ago, when it was time to rebuild my motor found out wrong head studs where boxed wrong. I made contact with NorCal Diesel Performance we verified that the part numbers matched on the box and inside the bag was wrong. They had no problem fixing my issues. I would definitely buy from this company again. Customer service was awesome to deal with. Shipping was fast as well both times.
