Procomp Electronics main caps are precision machined from superior-quality steel. They come available as stock replacements (straight bolt) or with splayed outer bolt holes. These extreme main cap sets consist of all 5 caps including the rear and front cap. Procomp Electronics main caps improve reliability in highly stressed engines by reducing distortion of the main bearing bores, and increasing the cap's resistance to closing up under high loads.
