ARP Ford 2.5L B5254 5-Cylinder Main Stud Kit (2005+)

This ARP Main Stud Kit replaces the factory main-cap fasteners on the 2005-and-later Ford 2.5L B5254 five-cylinder with high-strength studs for more accurate, repeatable clamp load and better main-bearing alignment under high power. Includes studs, hardened parallel-ground washers, and nuts.
