The connecting rods are made by Howard's Racing Cams (HRC) of Oshkosh, WI, and tip the scales at 550 grams. The 5.7-inch "Sport Lite" connecting rods are an I-beam design, more like factory rods than pricey aftermarket H-beam units. They are light, strong, and affordable. They ship with bronze bushings in place, ARP 7/16-inch capscrew bolts, special heat-treating, and are clearanced for strokers. They are also shot-peened and machined with alignment dowels in place (so the caps don't move) and are black-oxide coated. While Howard Cams claims these rods are good to 500 hp, Beck knows they can take a bit more.
