Vortex 828A-40 Aluminum Rear Sprocket 40 Tooth 520 Pitch

The Vortex 828A-40 is a high-performance aluminum rear sprocket designed for 520 pitch chain applications. This 40-tooth sprocket is precision-machined from lightweight 7075-T6 aluminum alloy, offering an excellent balance of strength and weight reduction compared to steel sprockets.

Key Features:

• 40 teeth configuration for optimized gearing ratios
• 520 pitch compatible for standard performance chains
• CNC-machined from aerospace-grade 7075-T6 aluminum
• Hard-anodized finish for enhanced wear resistance and durability
• Self-cleaning mud grooves prevent debris buildup
• Significant weight savings over OEM steel sprockets

Vortex sprockets are manufactured to exacting tolerances and undergo rigorous quality control testing. The lightweight aluminum construction reduces unsprung and rotational mass, improving acceleration and handling response. The hard-anodized surface treatment provides excellent corrosion resistance and extends service life.
