Renthal sprockets are CNC machined from cased hardened and core refined 655M13 nickel chromium steel. Mud grooves are then CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the sprocket. This unique design helps reduce wear and dramatically increases the lifespan of your drivetrain.

FEATURES

  • Precision CNC machined to extremely tight tolerances for maximum performance
  • Self-cleaning mud grooves between every tooth on both sides help prevent dirt build-up
  • Case hardened and core refined 655M13 Nickel-Chrome-Molybdenum alloy steel construction to give the ultimate combination of strength and hardness
