Built from billet steel, this one piece girdle is engineered to keep the OEM main caps sturdy by tying them all together. This will require the main caps be machined flat on the top, as well as having the engine line bored when done. We can offer this service IF we are building a complete engine. By tying the main caps together it creates a strong bond that keeps the caps from flexing or causing main bearing/crank issues that the 11-19 bottom ends are known for. This setup uses the "standard" ARP main studs, no need for custom studs! For questions about having engines built feel free to call in and talk with one of our knowledgeable salesmen!
