Vortex 826ZRV4-43 V4 Aluminum Rear Sprocket 530 Pitch 43 Tooth Silver

The Vortex 826ZRV4-43 is a 43-tooth, 530-pitch aluminum rear sprocket built on Vortex's newest V4 platform. Introduced in 2026, the V4 design delivers a 10–15% reduction in weight over Vortex's classic CAT5 sprocket without sacrificing structural integrity, thanks to an optimized lightening pattern and machined faces on both sides.

Key Features:

• V4 design — Vortex's latest platform offering 10–15% weight savings over the CAT5 generation
• 530 chain pitch — bolt-on OEM replacement for 530-pitch drivetrain setups
• 43 teeth — stock-equivalent tooth count for balanced acceleration and top speed
• 7075-T6 billet aluminum — aerospace-grade alloy for maximum strength-to-weight ratio
• 100% CNC machined in the USA — manufactured to tight tolerances for precise chain engagement
• Silver anodized finish — clear coating applied before cutting for corrosion resistance and the signature two-tone machined look
• Unique tooth profile — Vortex's patented tooth geometry extends sprocket service life
• Reduces rotating mass for improved throttle response, acceleration, and deceleration

Vortex aluminum sprockets are used by professional race teams worldwide and are among the most trusted drivetrain components in road racing, flat track, and supercross. For maximum longevity, chain cleaning and tension should be checked every 300–400 miles.
