Vortex 826ZLV4-43 V4 Aluminum Rear Sprocket 43 Tooth

The Vortex 826ZLV4-43 is a 43-tooth aluminum rear sprocket built on Vortex Racing's newly introduced V4 sprocket platform — the next generation of their iconic CAT5 design. Engineered for riders who demand maximum performance with minimum rotating mass, this sprocket is 100% CNC manufactured in the USA from a specially formulated aerospace-grade aluminum alloy developed to Vortex's exact specifications.

Key Features:

• V4 Design: Vortex's latest sprocket architecture, delivering a 10–15% reduction in weight compared to the previous CAT5 generation without sacrificing structural integrity
• 7075 T6 Billet Aluminum: Aerospace-grade alloy provides an exceptional strength-to-weight ratio, reducing overall rotating mass for improved throttle response
• 100% CNC Machined in the USA: Manufactured to tight tolerances for precise fitment and consistent performance
• Silver Anodized Finish: Clear protective coating applied before cutting gives the sprocket its signature two-tone machined look while guarding against oxidation and corrosion
• Unique Tooth Design: Vortex's patented tooth geometry promotes longer sprocket life and smooth chain engagement
• 43 Teeth: Suited for riders seeking enhanced low-end torque and acceleration from their gearing setup
• Wheel Fitment Code 826: Matches specific rear wheel bolt patterns — verify compatibility before ordering

Vortex Racing has supplied drivetrain components to professional road racing, motocross, supercross, flat track, and drag racing teams for decades. The V4 sprocket line builds on that heritage with refined design, material optimization, and improved weight balance. For best longevity, maintain chain cleanliness and proper tension every 300–400 miles when running aluminum sprockets.
