Why should I use main studs instead of stock bolts for my engine build?

Main studs provide more consistent and higher clamping force on the crankshaft main caps compared to stock bolts. This is important for preventing cap walk and ensuring the bottom end stays together, especially when increasing horsepower or boost.

What material are the ARP main studs made from?

The studs are manufactured from 8740 chromoly steel, a strong and durable material commonly used in performance engine components.

Does this kit include everything needed for installation?

Yes, the kit comes complete with the main studs, nuts, and washers required for installation.
