Ironman Sprockets are crafted from heat-treated nickel chromolly plated chrome-molly steel that is 2.5 times stronger than steel and is 2.5 times stronger than stainless steel and 3 times stronger than 7075 aluminum. Ironman Sprockets generally weighs18 ounces versus a 14-ounce 7075 aluminum from other name brands but makes up the difference in tremendous strength, especially if you consider the typical stainless steel or Tri-Moly sprocket weighs in at anywhere from 25 to 30 ounces. And better yet, these dirt bike motorcycle sprockets are made right here in the USA.
