When I had mine studded back in 2008, the dealership offered to do it under warranty as long as I supplied the studs. Truck was already under the knife for head gaskets. While shopping around, all the diesel supply houses wanted like $600-700 for ARP's it seemed. Found them on Ebay for less than $400 from a bunch of vendors but the price difference spooked me, I was afraid that they might be counterfeit. Cheap hardware in an ARP knockoff box. So I called ARP to get their feedback, curious if they were aware of their product being counterfeited, they told me no, not that they were aware of but they steered me toward one of their vendors. A small outfit, I almost had the feeling he was working out of his garage but ARP put me in contact so I knew the product was legit. He sold me mine for very little more than the ones on Ebay. Might be worth going to ARP again, they might point you toward someone hungry for business like they did me.
