Vortex 543A-48 Aluminum Rear Sprocket 48-Tooth

The Vortex 543A-48 is a 48-tooth aluminum rear sprocket engineered for serious street and track riders who demand precision, durability, and lightweight performance. Manufactured 100% in the USA using CNC machining, this sprocket is built to exacting tolerances for smooth power transfer and consistent engagement with every link of the drive chain.

Key Features:

• 100% CNC manufactured in the USA for precise tolerances and consistent quality
• Aerospace-grade aluminum construction reduces rotational mass for improved throttle response
• Anodized finish provides corrosion resistance and a distinctive two-tone machined appearance
• Vortex patented unique tooth design increases sprocket longevity and reduces wear
• 48-tooth rear sprocket raises the final drive ratio for improved low-end torque and acceleration
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio

Changing to a higher tooth count rear sprocket — such as the 48-tooth 543A — increases the front-to-rear gear ratio, delivering more low-end pull and quicker acceleration, ideal for tight circuits or aggressive street riding. The 543A-48 is a direct bolt-on upgrade that pairs seamlessly with Vortex front sprockets and chains for a complete drivetrain solution.
