Product Details

The Vortex 839AKV4-40 is a lightweight 40-tooth aluminum rear sprocket designed for use with the Vortex VTX quick-change sprocket carrier system. Engineered for performance street and track riders, this sprocket is precision CNC-machined from high-grade aluminum alloy, delivering an optimal balance of strength, durability, and reduced unsprung weight compared to steel alternatives.

Key Features:

  • 40-Tooth rear sprocket for optimized final drive gearing
  • CNC-machined from high-grade aluminum alloy for lightweight performance
  • Compatible with Vortex VTX AKV4 quick-change sprocket carrier system
  • Hard anodized finish for corrosion resistance and extended service life
  • Precision tooth profile for smooth, quiet chain engagement and reduced wear
  • Significant weight savings over comparable steel sprockets
  • Manufactured to tight tolerances for true, wobble-free rotation

The Vortex VTX sprocket system allows for fast gear ratio changes at the track without removing the rear wheel, making the 839AKV4-40 an ideal choice for racers and performance enthusiasts who want quick, tool-friendly sprocket swaps. Vortex sprockets are a trusted name in motorsports and are manufactured in the USA.

Great price and quick shipper. Thank you.

Ordered Enkei brand hubcentric rings, company sends Coyote brand hubcentric rings. Will they work, yes but it's a classic bait-n-switch sales tactic. Wish THMotorsports was upfront & honest with their customers.

First time buyer time will tell

Grate customer service

All good

Super smooth transaction, and fast delivery. Just waiting for my mechanic to open packages and verify all correct parts, but I don't expect any issues. Would definitely purchase and recommend others do business with Motorsport.com again

Only complaint is with UPS-paid for 2 day shipping, but evidently that does not include weekend. Ordered Wed night, THM processed on Thurs morning promptly. Didn't receive item till Monday. Other than that, A+ for THM.
