Renthal 479-520-13GP Steel Front Sprocket Pitch Grooved Sprockets - 13T 520

The Renthal 479-520-13GP is a 13-tooth front countershaft sprocket built for 520 pitch chain systems and engineered to handle the punishment of off-road and motocross riding. Precision-machined to tight tolerances, it ensures consistent chain engagement, reduced drivetrain friction, and extended component life.

Premium Steel Construction:

Manufactured from nickel-chrome-molybdenum steel and subjected to a precision case hardening process, this sprocket achieves an ideal balance of surface hardness for superior wear resistance and core toughness to absorb high torque loads without deformation.

Grooved Tooth Profile:

Strategic cut-outs at the base of each tooth allow mud, dirt, and debris to escape freely rather than packing between the sprocket and chain. This self-cleaning grooved design helps prevent the chain tension spikes and accelerated wear that debris buildup causes, keeping power transfer smooth and consistent in the most demanding conditions.

Key Specifications:

• Tooth Count: 13T
• Chain Pitch: 520
• Material: Nickel-chrome-molybdenum steel
• Finish: Case hardened
• Tooth Style: Grooved (self-cleaning)
• Position: Front countershaft

Renthal is a trusted name in motocross and off-road drivetrain components. The grooved profile makes this sprocket an ideal choice for motocross, enduro, trail, and off-road applications where mud and debris are a constant factor.
