Description

EC #40 19-Tooth Quick Change Sprocket – A-Type for EC Quick Change Hub


The EC #40 19-Tooth Quick Change Sprocket is engineered specifically for use with EC’s proprietary quick change hub system—delivering fast, tool-friendly gear changes and expanded gearing flexibility for racing transmissions like the Peerless 700.


This precision-machined A-Type sprocket (no hub extension) is designed to fit only EC quick-change hubs. It does not mount directly to Peerless 700 shafts, which were originally manufactured with either a 9-spline (coarse) or 36-spline (fine) output. EC developed two hub adapters (only the 36-spline version remains available) that convert those shafts to a common quick change interface, enabling easy swaps between 12T to 19T sprockets.


Whether you're chasing top speed or low-end torque, this 19-tooth sprocket allows you to fine-tune your final drive ratioto suit your engine, track, or terrain with minimal downtime.


Key Features:

  • Tooth Count: 19
  • Chain Pitch: #40
  • Type: A-Type (flat hubless design)
  • Fits: EC Quick Change Hubs only
  • Material: Precision-machined steel for durability
  • Use Case: Ideal for racing lawnmowers and high-performance drivetrain tuning


Compatibility Notice:

  • Will not fit directly on Peerless 700 series output shafts
  • Requires EC Quick Change Hub (36-spline model)
  • Not compatible with stock Peerless or other non-EC hub systems


Ideal For:

  • Racing Lawn Mowers
  • Performance Go-Karts
  • Custom Transmissions Using EC Quick Change System
  • Gearing Adjustments on Peerless-Based Builds

FAQ

1. Will this 19-tooth sprocket fit directly on a Peerless 700 output shaft?

No. This sprocket is not designed to mount directly to a Peerless 700 shaft. It must be used with the EC quick change hub, which adapts 36-spline shafts to EC's sprocket system.


2. What is an A-Type sprocket?

An A-Type sprocket is flat and has no built-in hub. It's designed to sit flush against a hub, like EC’s quick change system. It is lightweight and ideal for compact setups.


3. What chain does this sprocket use?

This sprocket is designed for #40 roller chain, which has a 1/2" pitch and is commonly used in racing lawnmowers, go-karts, and small industrial equipment.


4. What range of sprockets are available in EC’s quick change system?

The EC quick change system supports sprockets from 12 to 19 teeth, allowing racers and builders to quickly adjust gearing to match track layout or engine performance.


5. Why use a quick-change sprocket system?

Quick change systems let you swap sprockets without removing the hub, saving time and making tuning easier. It's perfect for racing or any performance-focused setup.


6. Is this sprocket compatible with any other hubs?

No. It is specifically designed to fit EC quick change hubs and is not compatible with OEM or other aftermarket hub designs.
