What is the purpose of the fan spacer?

The included .250 inch fan spacer helps to properly align your fan with the water pump pulley and belts. This ensures smooth operation and prevents premature belt wear.

What makes the 12-point head useful?

The 12-point head on the studs allows you to use a socket for installation. This provides better grip and allows you to tighten the studs more securely compared to a standard hex head.

What material are these studs made from?

The studs are made from heat-treated steel, which ARP uses to ensure they have solid strength and durability for engine components.
