Why use main studs instead of stock bolts?

Main studs provide more consistent clamping force and are stronger than stock bolts. This helps ensure the main caps stay securely in place, especially in performance applications or when rebuilding an engine.

What material are these studs made from?

These ARP main studs are made from a high-strength alloy steel. They are also heat-treated to increase their durability and resistance to stress.

Do I need any special tools to install these studs?

While the studs themselves are a direct fit, proper engine assembly requires specific tools for cleaning, measuring, and torquing. Always refer to the factory service manual for your specific vehicle for detailed installation procedures.
