The Vortex 438ZUV4-45 is a high-performance CNC-machined aluminum rear sprocket featuring 45 teeth, designed for UTV and side-by-side applications. Engineered to replace the heavier stock steel sprocket, this lightweight aluminum unit reduces rotating mass for improved throttle response, acceleration, and overall drivetrain efficiency.

Key Features:

• 45-Tooth Rear Sprocket — optimized tooth count for performance gearing adjustments
• Lightweight Aluminum Construction — specially formulated alloy per Vortex specifications, significantly lighter than OEM steel
• 100% CNC Machined in the USA — manufactured to the tightest tolerances for perfect concentricity every time
• Vortex Patented Tooth Design — unique profile reduces friction and drag, extending both sprocket and chain service life
• Lightening Holes — strategically placed cutouts further reduce rotating mass without sacrificing strength
• Clear Anodized Finish — protects the aluminum surface against corrosion and wear
• ZUV4 Hub Pattern — designed specifically for compatible UTV/side-by-side bolt configurations

Vortex Racing sprockets are a trusted choice among performance riders and racers. Reduced rotating mass translates directly to improved acceleration and deceleration response. Each sprocket is produced in the USA to exacting quality standards, ensuring a perfectly concentric fit that protects your chain and extends drivetrain longevity.
