Description

EC #40 16-Tooth Quick Change Sprocket – A-Type for EC Quick Change Hubs


The EC 16-Tooth Quick Change Sprocket is a precision-machined A-Type sprocket, purpose-built for use with the EC Quick Change Hub system. Made for #40 pitch chain, this sprocket is ideal for racers and builders who need quick, reliable gearing changes to fine-tune performance for varying track layouts or torque requirements.


With a 16T configuration, it offers slightly more torque than a 17T or 18T option—making it a strong choice for tracks with tight turns or for builds that need quicker acceleration off the line.


Note: This sprocket does not fit directly onto Peerless 700 shafts. It is compatible only with EC Quick Change Hubs designed for 36 fine spline output shafts.


Key Features:

  • Tooth Count: 16
  • Chain Pitch: #40
  • Type: A-Type (flat sprocket with no hub extension)
  • Material: High-strength machined steel
  • Fitment: EC Quick Change Hub only (not compatible with OEM shafts)


Benefits:

  • Quick-change capability—swap gearing without removing the hub
  • Enables fine-tuning of final drive ratio for better throttle response
  • Lightweight A-Type design reduces rotating mass
  • Compatible with EC's full sprocket lineup (12T–19T)


Applications:

  • Racing Lawn Mowers
  • Go-Karts & Mini Bikes
  • Peerless 700 Transmissions with EC Quick Change Hub
  • Performance Engines Requiring Mid-to-Low Gear Ratios

FAQ

1. What hub does this sprocket require?

This sprocket is made specifically for the EC Quick Change Hub (36 fine spline). It will not work directly with stock Peerless 700 shafts.


2. What is the performance effect of using a 16T sprocket?

A 16T sprocket gives you more low-end torque compared to larger tooth counts. It's ideal for tight, technical tracks or builds focused on acceleration.


3. What type of chain does this sprocket use?

It uses #40 pitch roller chain, commonly used in small-engine, kart, and racing lawn mower applications.


4. What is an A-Type sprocket?

An A-Type sprocket is a flat sprocket with no built-in hub. It mounts directly to the EC Quick Change Hub, keeping your drivetrain light and simple.


5. Can I use this sprocket with other hubs?

No. This sprocket is only compatible with EC’s proprietary quick change hub and will not fit OEM or other aftermarket hubs.


6. What range of EC quick change sprockets is available?

The EC quick change system includes sprockets from 12 teeth to 19 teeth, allowing for easy tuning of your gear ratio depending on the track and power output.
