What material are these head bolts made from?

These head bolts are made from strong 8740 chromoly steel, a material known for its durability and ability to withstand high stress applications. They also feature a black oxide finish for added corrosion resistance.

Do these bolts come with everything needed for installation?

The kit includes the head bolts and a packet of ARP５0W racing oil for lubricating the threads and washers. It is recommended to have a torque wrench and follow the manufacturer's specific torque sequence for proper installation.

What is the benefit of rolled threads versus cut threads?

Rolled threads are stronger than cut threads because the material is displaced rather than removed. This process increases the fatigue strength of the bolt, making it more resistant to breaking under stress.
