Description

EC 4084 Quick Change Hub – 36 Fine Spline for Peerless 700 Transmission


The EC 4084 Quick Change Hub is engineered to simplify and speed up gear ratio adjustments on Peerless 700 Series transmissions equipped with a 36-tooth fine spline output shaft. Designed specifically for performance and racing applications, this hub allows for rapid sprocket swaps using EC’s line of quick-change sprockets.


Peerless 700 transmissions were manufactured with two different output shaft types:

  • 36 fine spline (this hub fits)
  • 9 coarse spline (no longer supported)

This hub is compatible only with the 36-spline shaft, which is the more common configuration in racing and high-performance builds. By converting the shaft to EC’s quick-change sprocket system, you gain access to a wide range of gearing options — from 12 to 19 teeth — giving you the flexibility to fine-tune your drivetrain for track conditions, terrain, and engine characteristics.

Note: This hub is not compatible with 9-spline shafts or OEM sprocket setups.


Key Features:

  • Converts Peerless 700 fine spline shaft for use with EC quick-change sprockets
  • Designed for 36-tooth fine spline output shafts
  • Enables fast gearing adjustments without removing the hub
  • Compatible with EC sprockets ranging from 12T to 19T
  • Precision-machined for secure fit and long-lasting durability
  • Ideal for racing lawnmowers and performance-driven setups


Ideal For:

  • Peerless 700 Transmission (36-spline only)
  • Racing Lawn Mowers
  • High-Performance Drivetrain Setups
  • Gearing Customization and Track Tuning
