Description

EC #40 18-Tooth Quick Change Sprocket – A-Type for EC Hubs


The EC 18-Tooth Quick Change Sprocket is part of our precision-machined A-Type sprocket line, built specifically for use with the EC Quick Change Hub system. Designed for #40 pitch chain and optimized for performance, this sprocket offers a simple, fast way to fine-tune your drivetrain gearing—ideal for racing lawnmowers, go-karts, and custom Peerless-based transmissions.


This 18-tooth version sits just below the 19T in gear ratio, giving you slightly more acceleration with only a minor reduction in top speed—perfect for tracks requiring quicker low-end response.


Important: This sprocket does not fit directly onto Peerless 700 output shafts. It is compatible only with EC Quick Change Hubs (36 fine spline version).


Key Features:

  • Tooth Count: 18
  • Chain Pitch: #40
  • Type: A-Type (flat, no hub)
  • Material: Precision-machined steel for durability
  • Fits: EC Quick Change Hubs (not direct-to-axle or transmission)


Benefits:

  • Enables fast, easy gearing changes at the track
  • Supports tighter tuning of final drive ratio
  • Ideal for performance builds requiring flexibility and durability
  • Works with EC’s 12–19 tooth quick-change sprocket lineup


Applications:

  • Racing Lawn Mowers
  • Go-Karts
  • Peerless 700 Series Transmissions with EC Hub
  • Custom Performance Drivetrains

FAQ

1. What is this sprocket designed for?

This 18-tooth sprocket is built for #40 pitch chain and designed to fit only EC Quick Change Hubs. It allows for fast gear ratio adjustments without removing the hub.


2. Will this fit directly on a Peerless 700 output shaft?

No. It will not fit directly on a Peerless transmission shaft. It is compatible only with the EC Quick Change Hub (36 fine spline version).


3. What is the benefit of an 18T sprocket over 19T or 17T?

The 18T sprocket offers a balance between acceleration and top-end speed. It’s great for track conditions that require strong mid-range performance.


4. What is an A-Type sprocket?

An A-Type sprocket is a flat sprocket with no integrated hub. It mounts flush against the EC Quick Change Hub, offering a compact and lightweight setup.


5. What chain size does this work with?

This sprocket is made for #40 pitch roller chain, commonly used in racing go-karts, lawnmowers, and performance equipment.


6. Can I swap between EC sprockets easily?

Yes! That’s the purpose of the quick change system. You can switch between 12T–19T sprockets quickly without removing the hub, saving time at the track.
