there is many lite weigh steel rods. small journal rods scat .lunati.wheeler.howards .crowers. and many more . they all make a lite steel rod . good aluminum rods are not cheap. a stock rework rod with good bolts will do for you. but it may be cheaper. buy a set of new steel rods. there is a very limited place for aluminum rods. and they need to be replaces after a limited amount of runs they may look great on a rebuild BUT they can fail if runed past there time
