The Vortex 435KV4-48 is a 48-tooth, 520-pitch aluminum rear sprocket from Vortex's industry-trusted 435 series. Designed as a high-performance, lightweight alternative to heavy OEM steel sprockets, this sprocket is finished in Vortex's CAT5 color anodizing for a striking appearance and added corrosion resistance.

Key Features:

• 7075 T6 Aerospace Aluminum Construction — Computer-designed and CNC-machined from high-grade 7075 aluminum for exceptional strength-to-weight ratio
• CAT5 Color Anodized Finish — Electrically coated for a brighter shine; color anodizing applied to the body while sweeps, mud grooves, and teeth remain natural for a distinctive two-tone look
• 100% CNC Manufactured in the USA — Machined to the tightest tolerances, ensuring a perfectly concentric sprocket every time
• Vortex Patented Tooth Design — Unique saber tooth profile reduces friction and drag, improving both acceleration and deceleration while extending sprocket and chain life
• Lightening Holes — Strategically placed to reduce rotating mass; less rotational weight translates directly to improved throttle response and acceleration
• Mud Grooves — Help keep the drive components clean under varied riding conditions
• 520 Chain Pitch — Compatible with 520-size OEM chains or suitable 520 conversion setups
• 48 Teeth — Available in single-tooth increments across the 435 series for precise gearing customization
