Product Details

The Vortex 839AZUV4-40 is a 40-tooth aluminum rear sprocket from Vortex Racing's VTX series, engineered for riders who demand lightweight performance without sacrificing durability. Precision-machined from high-grade aluminum alloy and finished with a hard anodized coating, this sprocket delivers excellent wear resistance and corrosion protection across street and track applications.

Key Features:

  • 40-Tooth Rear Sprocket — bolt-on replacement for fine-tuning final drive ratio
  • Lightweight Aluminum Construction — significantly reduces unsprung rotational weight compared to steel sprockets
  • Hard Anodized Finish — resists wear, corrosion, and chain abrasion for extended service life
  • CNC Precision Machined — tight tolerances ensure smooth, quiet chain engagement
  • VTX Series Design — features Vortex's signature scalloped carrier for additional weight savings
  • Direct OEM Replacement Fitment — matches factory sprocket bolt pattern and chain pitch

Vortex is a trusted name in the motorsports and powersports industry, supplying sprockets to professional race teams and performance street riders worldwide. The 839AZUV4-40 is an ideal upgrade or replacement for riders looking to optimize acceleration, top speed, or fuel efficiency through gearing adjustments.

Informative and helpful ordered tires and the process was smooth. Shipping company was quite slow compared to others that we've ordered from buy tires just showed up and seemed to be good. Thank you.

Very good, Item was as expected

The ordering process was simple and the tire was shipped quickly. My overall experience was great and I would order from Motorsport.com again!

The website was easy to navigate and your facility was the only one that had the product.

Very quick, very easy…thank you
