What is a windage tray and why is it included?

A windage tray is a component installed in the crankcase that helps to keep oil from being excessively splashed around by the rotating crankshaft. This can improve engine efficiency by reducing drag and preventing oil from being aerated.

What is the advantage of splayed main caps?

Splayed main caps have their outer bolts angled outwards, which helps to distribute stress more evenly and increase the rigidity of the main bearing saddles. This is often beneficial in high-performance applications where increased clamping force is needed.

What material are these main studs made from?

These main studs are made from ARP's proprietary 8740 alloy steel, which is heat-treated to provide excellent strength and durability for demanding engine applications.

Product Details

If you're rebuilding the bottom end of your Small Block Chevy engine, especially one that's going to see some serious use, you'll want to make sure the main caps are held down securely. This main stud kit from ARP is designed to do just that, offering a stronger hold than stock bolts. It includes studs specifically designed for splayed main caps, which are often used in performance applications to increase rigidity around the crankshaft. Plus, this kit comes with a windage tray, which helps to reduce oil splash and improve engine efficiency by keeping oil from being thrown around unnecessarily.

ARP is well-known for making strong fasteners, and these main studs are no exception. They're made from a proprietary ARP 8740 alloy steel, which is heat-treated to ensure it can handle the stresses of a performance engine. The threads are rolled after heat-treating, which makes them stronger and more resistant to fatigue. The kit includes the necessary nuts and washers, all made to ARP's high standards. Installing these studs is a key step in ensuring your engine's bottom end stays together under load.
