What is the advantage of 12-point bolts over standard 6-point bolts?

12-point bolts offer a tighter fit and allow for more leverage when you're tightening them down. This can be helpful in tight engine bays or when extra torque is needed.

What material are these ARP bolts made from?

These ARP bolts are made from heat-treated steel. This material provides solid strength and reliability for your engine's cooling system components.

Does this kit include all the necessary hardware to install the water pump and thermostat housing?

Yes, this kit includes both the water pump bolts and the thermostat housing bolts needed for installation on compatible GM LS1 and LS2 engines.
