Product Details

The Vortex 312ZB-57 is a 57-tooth, 520-pitch aluminum rear sprocket finished in a satin black anodized coating. Designed for performance street and track riders, this sprocket is CNC-machined from high-grade aluminum, delivering an ideal balance of strength and reduced rotating mass for improved throttle response and acceleration.

Key Features:

  • 57-Tooth / 520 Pitch: Designed to increase low-end torque and acceleration compared to stock gearing
  • CNC-Machined Aluminum Construction: Lightweight design reduces rotational mass for improved performance
  • Black Anodized Finish (ZB): Satin black anodized coating provides corrosion resistance and a clean, aggressive look
  • Vortex Patented Tooth Design: Unique tooth profile engineered for optimal chain engagement, smooth operation, and extended sprocket life
  • 520 Chain Pitch Compatibility: Designed for use with standard 520-pitch chains
  • USA Manufactured: Precision-manufactured to tight tolerances for consistent fit and long-lasting performance

The Vortex 312ZB-57 rear sprocket is a direct-fit upgrade for riders looking to fine-tune their gearing for the street or track. Pair with a matching 520-pitch front sprocket and chain for a complete drivetrain refresh.

Very fast shipping with standard rates. I was surprised!

Good experience

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.

I had ordered some CM-19546-A2 (friction-modifier for posi-traction differentials with carbon-fiber clutches) from CJ Pony Parts, and it arrived broken and had all leaked out. I spent $25.42 for nothing, and they still have not responded to my complaint. I bought 2 bottles from THMotorsports in hopes that ONE would arrive undamaged. They arrived in a box, not a bubble mailer like CJ, and both bottles were intact and undamaged. If you're going to buy specialty automotive fluids online, THMotorsports is the better place to do so.

Easy to order

Best price. Easy transaction
