Our premium rods, custom made for us by SaenzPerformance Not only are these rods custom made to spec between RMB and saenz’s engineers, but they are sexy. Use of a large 12pt head and a 7/16 ARP 2000 or ARP 625+ rod fastener kicks off this party. These rods are our premiere offering, and between the detailed balancing of weight VS strength we feel this is a hard I-Beam rod to beat bar none. Pick them up in your hand, and you know why. In stock, ready to ship, or use on your build.
