• 【Confirm Compatibility】This rear sprocket features 68mm mounting hole spacing (center to center of hole) for holes opposite each other on the sprocket. Mounting holes adjacent to each other are spaced at 48mm (center to center of hole). Please refer photo number 2 for detailed dimensions
• 【Quality Make & Materials】We pride ourselves on the quality at which we produce this rear bike sprocket. The sprocket gear itself is made of premium-quality steel, excellent corrosion resistance and longer-lasting composition
• 【High Tech Heat-treatment】Heat-treatment hardens the metal, improves the strength, allowing it to withstand wear and tear better. The sprocket features a unique radius curve for each tooth in the gear which helps reduce transmission friction, which in turn helps extend the life of your chains
• 【Attention】420 Sprockets are compatible with 420 type chains only! Please confirm that your ATV or quad has a 420 sprocket. Additionally, youth and Children’s size ATVs utilize 420 or 428 chains only. Please check the chain size on your ATV by closely inspecting a link on your existing chain for size and pitch markings before selecting a new sprocket
• 【Important Note】Without changing the front sprocket, reducing the size (number of teeth) in the rear sprocket will increase top speed but reduce torque. Increasing the size (number of teeth) in the rear sprocket will increase torque allowing for greater hill climbing but will reduce the top speed
