ARP Bolts are used by virtually every top professional engine builder. Simply put, there is no better bolt setup on the market today.

These main bearing studs are manufactured to exacting tolerances, heat treated, centerless ground and rolled to ensure consistent clamping force and durability. Only premium grade 8740 alloy with a tensile strength of 190,000 psi is used, which is far superior to "aircraft grade" steel alloys. Studs allow for easy installation of cylinder heads and gaskets, eliminating the need for alignment.

These ARP studs fit all 1.8T engines and are ideal for racing engines.
