I have the same long rod from Vegas I got for a special build. I was looking through NR Racing parts and found an upgraded set of rod bolts. They had a real high tensile strength that I liked. I also saw a video which had an original bolt snap. I changed them this afternoon, I was impressed -- the main bolt body was much larger. I would recommend these to anyone using this rod for a special build. After you handle and change them out you'll know it was the right way to go.
