ARP Main Stud Kit for all 2 Bolt Main Iron Blocks 4.6L / 5.4L without Windage Tray

2 Sets of these can be used for the 5.4L / 5.8L Aluminum Blocks, which have 10mm Inner and Outer bolt holes
Pricing: $142.99


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 / 5.4L Iron Blocks without a Factory Windage Tray, including the Boss 5.0L Block.
  • Highly Recommending on all High RPM Applications or any engine making over 500 HP
  • 2 Sets needed for 5.4L / 5.8L Aluminum Blocks with 10mm Inner and Outer bolt holes
