ARP 2000 Series Main Stud Kit – Nissan RB20, RB25 & RB26

As the power increases so does the stress on the bolts that hold 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.
