Rekluse Clutch Slave Cylinder Assembly For Harley Touring / Softail 2017-2020
Rekluse Manual Slave Cylinder: The Ultimate Hydraulic Fix for the M8 Era
The Rekluse Manual Slave Cylinder is the premier drivetrain upgrade for 2017–2020 Harley-Davidson models equipped with hydraulic clutches. While the Milwaukee-Eight engine provides impressive power, the stock hydraulic actuator often suffers from a heavy pull and a dangerously narrow friction zone. Rekluse solves these issues with a precision-machined assembly that re-gears the mechanical advantage of your clutch, delivering a 30% reduction in lever effort and a much more predictable feel.
Expanded Friction Zone & Better Modulation
The factory M8 hydraulic clutch is notorious for engaging at the very end of the lever travel, making it difficult to control during tight turns or stop-and-go riding. The Rekluse Slave Cylinder widens the friction zone and shifts the engagement point closer to the handlebar. This allows for superior modulation, smoother take-offs, and a level of control that feels more like a traditional cable clutch than a stiff hydraulic system.
Billet Construction vs. OEM Plastic
Standard factory slave cylinders often use plastic internal components that can warp or fail under the high heat generated by the exhaust and engine. The Rekluse unit is CNC-machined from 6061-T6 billet aluminum and finished with a hard-anodized coating. This ensures maximum seal integrity and durability, preventing fluid bypass and the “clutch creep” that can occur when the engine is hot.
Performance Compatibility
This unit is a direct “bolt-on” replacement and is compatible with both stock and aftermarket clutch packs. When paired with the Rekluse TorqDrive clutch, riders can see a combined lever pull reduction of up to 60%, making it the ultimate setup for high-horsepower builds or riders with hand injuries/arthritis.
Fitment and Compatibility (2017–2020)
This unit (Part #RMS-2415050) is designed specifically for M8 models with hydraulic actuation:
- Touring: 2017–2020 Street Glide, Road Glide, Road King, and Electra Glide (including CVO models).
- Softail: 2017 “S” Series models (FLSS, FLSTFBS, FXSE) and other limited hydraulic Softail applications.
- Note: Not compatible with 2021-later models that transitioned back to a mechanical cable clutch.
Rekluse Clutch Slave Cylinder Assembly For Harley
The Rekluse slave cylinder was designed to create a mechanical advantage which reduces lever pull by over 30%, widening the friction zone while moving the modulation point closer to the handlebars. The hard anodized billet aluminum construction provides enhanced sealing and maximum durability. Rekluse has years of experience engineering and manufacturing high performance billet slave cylinders for motorcycle applications, making this a proven solution you can trust.
