ARP Main Stud Kit for all 4.6L 4 Bolt Main Aluminum Blocks with 3V Full Length Windage Tray

Every 4.6L / 5.4L Engine we have ever disassembled with a broken oil pump showed signs of main cap walk and still had factory main bolts. We have assembled hundreds of engines using the stock oil pumps with ARP Main Studs and not had a single bearing or pump failure. With that being said, this is not an area to cheap out on. ARP Main Studs are a must for all performance engine builds and we would never assemble a performance engine without them!

• Fits all 4.6L Aluminum Blocks with Full Length 3V Windage Tray 
• Includes 8 Longer Studs for mounting Windage Tray 
• Highly Recommending on all High RPM Applications or any engine making over 500 HP.
