Vortex 526AV4-46 V4 Aluminum Rear Sprocket 520 Pitch 46-Tooth Silver

The Vortex 526AV4-46 is a 46-tooth, 520-pitch aluminum rear sprocket built on Vortex Racing's all-new V4 platform — the next evolution beyond the legendary CAT5 design. Engineered for street riders and racers who demand maximum performance with minimum rotating mass, the V4 delivers a 10–15% weight reduction over its predecessor without sacrificing structural integrity.

Key Features:

• V4 Design: New lightening pattern with machined faces on both sides for superior weight savings and a premium two-tone appearance
• 7075 Aluminum Construction: CNC machined from a specially formulated alloy per Vortex specifications for exceptional strength-to-weight ratio
• 100% CNC Manufactured in the USA: Precision machined to the tightest tolerances for concentricity and consistent performance
• Silver Anodized Finish: Clear protective coating applied before machining, resulting in Vortex's iconic two-tone silver look while resisting oxidation
• Unique Saber Tooth Groove Design: Vortex patented tooth geometry increases sprocket longevity and is unlike any other sprocket on the market
• 520 Pitch / 46 Teeth: Compatible with standard 520-pitch chain setups
• Trusted by professional race teams and champions worldwide

Aluminum sprockets reduce rotating mass compared to steel, helping the drivetrain feel more responsive and putting more power to the pavement. For optimal longevity, keep the chain clean and properly tensioned — Vortex recommends cleaning every 300–400 miles on bikes equipped with aluminum sprockets.
