Can I add ARP Case Bolts to an IAG Short Block or Case once it is built or machined?
Last Updated: 06/29/2018
Adding ARP case bolts to an IAG Short Block or IAG Case Half Set after it is machined and built to spec originally with OEM case bolts will cause case distortion and reduce the longevity of the engine. ARP case bolts require line honing the case and this process can only occur during the build/manufacturing process. If you want to upgrade an already assembled short block or machined case half set that was originally spec’d to OEM case bolts to ARP case bolts, it will require disassembly, line honing the case and new bearings at a minimum.
