The Belt Drives Ltd M18S-B is a complete 2-inch open primary belt drive kit designed specifically for Harley-Davidson M8 Softail models from 2018-2020, excluding Breakout and Fat Boy models. This high-performance upgrade replaces the stock primary drive system with a durable belt-driven design.

Key Features:

  • Two-piece motor plate design with black finish
  • 2-inch wide primary belt for enhanced power transfer
  • 52/69 pulley combination providing a 1.32:1 final drive ratio
  • Six-bolt diaphragm clutch configuration for firm feel and improved appearance
  • Ball bearing pressure plate for smooth operation
  • Enhanced springs and spring collar for positive lock-up engagement, ideal for high-horsepower applications
  • Counterbored front pulley cover for super-clean appearance
  • Includes side and top guard for aggressive open dome look
  • Made in the USA

This kit features matched pulley and belt profiles that are unique to each application. The front pulley face and spring collar have a matching pattern to the rear pulley for optimal performance. Professional installation recommended.

Everything ok

Quick and easy

It’s the second time I ordered from here. The first time was a great experience. Prices were reasonable and shipping was quick.

First off, the shipping was very quick! The battery was packaged very well. So, far so good. Just installed it in my SUV last night. Perfect fit! Thanks THMotorsports!

Everything was great. Shipping was fast and the price was lower than everywhere else.
