ARP SB Ford /WP Manowar Iron/Alum Block Main Stud Kit

ARP is well-known for making strong fasteners, and this main stud kit is no exception. If you're rebuilding the bottom end of your Ford small block engine, especially one with an iron or aluminum block, these main studs are a solid choice for securing the crankshaft main caps. They replace the weaker factory bolts, offering a more reliable way to keep everything tight under stress.

These studs are made from ARP's proprietary 8740 chromoly steel, which is heat-treated to give it a tensile strength of 200,000 psi. This means they can handle the increased clamping forces needed when you're building a performance engine or just want the peace of mind that comes with using stronger parts. The kit includes the necessary nuts and washers, all made to ARP's usual standards for precision and durability. Using studs instead of bolts also makes it easier to properly align and torque your main caps during assembly, which is crucial for a smooth-running engine.
