Chain/Sprocket Kit / 120 Link Non O-Ring Chain, Ironman Sprockets

Kit Includes:
• Ironman countershaft and rear sprockets.120 Link Regina Non-O-Ring Chain
• This is top of the line gold non O-ring motocross chain. Designed and developed to withstand the severe stresses caused by Motocross riding and racing. Larger diameter alloy carbon steel pins and thicker plates offer increased tensile strength and fatigue resistance. RX chains feature extended bushings, solid rollers, shaped bushings, and special chromized alloy carbon steel pins. Shaped bushings feature a “barrel” effect that occurs when a standard bushing is assembled. The result is full contact between bushing and pins along the entire length, with a subsequent reduction in specific contact pressure and hence, reduction in wear. The pins have exceptional surface hardness through a special chromizing treatment. This translates into maximum wear resistance.

Sprocket Features:
• High quality heat-treated chrome-moly steel which is 2.5 times stronger than steel and 3 times stronger than 7075 alloy.
• 250,000 psi material in a protective nickel heavy duty industrial finish.
• NEW "Closed Truss" design on rear sprockets (photo is old style) more evenly distributes stresses in the rare event of a missing sprocket bolt. This decreases stress levels everywhere, allowing for an overall decrease in weight.
• Countershaft (front) sprockets are made of shock-resistant die steel, much stronger than "case hardened" steel.
• Ironman sprockets come with a 1-Year manufacturer guarantee against wear! That's right! We're so confident your Ironman Sprocket will outlast anything you've ridden before, Ironman guarantees it against wear for a full year!
• Absolutely the toughest racing sprockets made.
• U.S. Made. Why buy aluminum when this sprocket weighs just a few ounces more.
