Product Details

The Vortex 313ZB-40 is a 40-tooth black anodized aluminum rear sprocket built to the exacting standards that have made Vortex Racing a go-to choice for street and track riders alike. Engineered for performance and durability, this sprocket delivers precise power transfer while reducing rotating mass compared to a stock steel unit.

Key Features:

  • 40 teeth — direct-fit replacement or gearing upgrade option
  • Black anodized finish with contrast machined accents for corrosion resistance and aggressive styling
  • 100% CNC manufactured in the USA from a specially formulated aluminum alloy per Vortex specifications
  • Patented tooth design for superior chain engagement and extended sprocket life
  • Reduced rotating mass compared to steel sprockets aids throttle response and rear-wheel power delivery
  • Precision machined to tight tolerances for concentricity and smooth chain tracking

The Vortex 313ZB-40 is a premium upgrade for riders seeking to fine-tune their gear ratio, replace a worn OEM sprocket, or reduce unsprung rotational weight — all without sacrificing reliability under demanding conditions.

Great price

Great experience... fast shipping

So excited to find this website. Awesome agent & prices for budget friendly shoppers. Thank you thank you!!!!

boatplicity provided the prop paint product that I needed and wanted at a very good price. Why pay the overpriced WM item? Ordering was easy, the free shipping option was a great feature and helped me go with boatplicity for my order. Shipping time was good. Didn't need it immediately and I loved the opportunity to use their offer.

During a regular boating season I usually damage one aluminum prop per year . Once again, I needed to replace my prop on a 50hp outboard that I use during fishing and deer hunting on the Missouri River. In past years I have had to allow time for the new prop to arrive. Not this time! The people at Boatplicity got the prop to me the very next day! And I paid the lowest price I have ever paid for the prop. I now have Boatplicity on my favorites list and will definitely use them for all my boating needs.

Good prices and your checkout system is easy to use. Thank you!

Good

Package shipped and arrived very quickly at a great price. Only suggestion would be to place the original packaging in an outer package as the box it arrived in appeared to be a little worn.

Great selection and prices.
