Dart main caps are made from superior-quality steel, iron or aluminium, which has the proper balance of strength and flexibility to allow for the transfer of increased shock loads to the crank and bearings. The main caps help 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.
