When it comes to extracting more power out of your engine the standard bolts are only good for standard HP/KW figures. As the power increases so does the stress on the bolts that h old the engine together therefore you need to upgrade to studs. This can be a confusing exercise as there are many different materials that the studs can be made out of and different thicknesses bigger is not always better. ARP studs are designed to go in without drilling or tapping so they are a direct replacement and piece of mind for your expensive investment.
