          Main caps side bolts

          Bolts were in genuine Ford motorsports box. No complaints. There's none better except Arp .

          Replacement bolt set for main bearing caps in aluminum blocks

          These are great genuine replacement bolts for the aluminum block. The set comes with two types of main bolts: 10 thread top bolts and 6 regular bolts. This allows you to set up different configurations for applications that may require several fastening points on the bottom end, such as custom-made Windage Trays. The set is configured for the 2005-2010 3-valve engines, but most of the bolts can be used in earlier models such as in my 97 Teksid block. The only variance is the diameter of the side bolts, which are reusable; so you will have to reuse the ones in earlier blocks. The only downside to the set is the total lack of installation instructions or any kind of technical write-up with the package. This is typical with Ford Racing parts. But the parts themselves are of great quality and will fit your Ford without hick-ups. In this particular set, there are no installation instructions on the Ford Racing site, so it is presumed that these follow the same installation procedures as the original bolts.
