Vortex 526ZGV4-44 Aluminum Rear Sprocket Pitch Green Sprockets - V4 520 44T

The Vortex 526ZGV4-44 is a 44-tooth, 520-pitch aluminum rear sprocket built on Vortex Racing's newest V4 design platform. Introduced in 2026, the V4 design delivers a 10–15% weight reduction over the iconic CAT5 pattern without sacrificing structural integrity, thanks to an optimized lightening cutout pattern with fully machined faces on both sides.

Key Features:

• V4 Design: Next-generation sprocket pattern with 10–15% less weight than the classic CAT5 for reduced rotating mass
• 520 Pitch: Designed for 520-pitch chain applications, including OEM replacements and 520 conversions
• 44 Teeth: Tuned rear gearing for improved low-end torque and acceleration response
• Green Anodized Finish: Anodized color coating applied before CNC cutting, producing the iconic two-tone machined look
• Specially Formulated Aluminum Alloy: Made to Vortex's own alloy specifications for optimal strength-to-weight ratio
• 100% CNC Manufactured in the USA: Precision-machined at Vortex's Salt Lake City, UT facility
• Patented Tooth Design: Vortex's unique saber tooth profile increases sprocket longevity and improves chain engagement
• Silver Machined Accents: Contrasting machined highlights complement the anodized green body

Aluminum sprockets are the preferred choice for road racing, track days, and performance street riding where weight savings translate directly into throttle response and acceleration. Regular chain cleaning every 300–600 miles is recommended to maximize the life of aluminum sprockets.
