Maximize your transmission's performance and service life with the Dr. Pulley Variator Slide Set. Often overlooked, these "ramp guides" are critical for the smooth movement of your variator. By pairing your high-performance slider weights with these matching Dr. Pulley slides, you eliminate the friction and "sticking" that can occur with worn factory plastics. This ensures a more responsive throttle and consistent gear-ratio transitions across the entire RPM range.
Technical Performance Features
- Self-Lubricating Polymer: Manufactured from a specialized low-friction material that reduces heat buildup and resists the "notching" common in standard OEM slides.
- Precision Fitment: Engineered to eliminate "slop" or rattling within the variator assembly, resulting in a quieter, smoother-running CVT.
- Enhanced Durability: Highly resistant to the thermal stresses of high-RPM racing and daily commuting, outlasting standard nylon guides.
- Optimized for Dr. Pulley Weights: Specifically designed to match the movement profile of sliding roller weights for the ultimate transmission setup.

Mechanic's Note: Slide sets are the most neglected part of a CVT tune-up.
Diagnostic Tip: If your scooter feels like it's "stuck in gear" or won't shift smoothly, your slides are likely worn or melted.
Pro Tip: Never reuse old slides when installing new Dr. Pulley Sliding Weights — worn guides can cause your new weights to flip or wear prematurely!
