Dr. Pulley 23x18mm Variator Sliders Eliminate variator "clatter" and restore smooth shifting with the Dr. Pulley Variator Slide Set . Unlike standard plastic guides that wear quickly and cause sticking, Dr. Pulley sliders are manufactured from a proprietary, self-lubricating nylon compound. Designed for the large-format 250cc and high-performance GY6 variators, these pieces provide the low-friction interface necessary for the ramp plate to move effortlessly, ensuring consistent acceleration and extended CVT life. Technical Performance Features Proprietary Low-Friction Material: Features Dr. Pulley’s signature heat-resistant nylon, which eliminates the need for messy grease and resists "flat-spotting" under high-load conditions. Precision Anti-Rattle Fit: Engineered to tighter tolerances than OEM guides, reducing internal vibration and protecting your variator housing from premature wear. Extreme Heat Stability: Maintains its structural integrity and lubricity even in the high-temperature environment of long-distance maxi-scooter touring. Long-Life Durability: Outlasts standard slider pieces by up to 3x, making it the ideal choice for heavy-duty commuters and performance tuners alike.

Slide pieces are the most overlooked part of CVT maintenance; if they are cracked or loose, your variator cannot "shift" smoothly, leading to flat spots in your acceleration. Pro Tip: Always clean the ramp plate channels with brake cleaner before installing these new sliders to ensure a grit-free surface.
