Dr. Pulley 16x13 Sliding Roller Weights - Performance CVT

Dr. Pulley Sliding Weights (16x13) — Performance CVT Tuning

Upgrade your CVT system with Dr. Pulley Sliding Roller Weights. Unlike traditional round weights, these uniquely shaped sliders allow the variator to open wider, increasing top-end speed, while providing a more aggressive response off the line.

Crafted from a proprietary self-lubricating nylon composite, these weights are designed for maximum longevity, high-temperature resistance, and reduced friction.

Key Performance Benefits

• Higher Top Speed: The sliding shape allows the variator to travel further than standard rollers
• Eliminates Flat Spots: Smoother, more consistent power band throughout the rev range
• Long-Lasting Durability: Specialized nylon reduces wear on both weights and the variator ramp
• Self-Lubricating: Protects variator inner surfaces and prevents flat-spotting

Weight Selection Guide

• Lighter (3.0g – 5.5g): Best for quick acceleration and hill climbing; runs at higher RPMs
• Standard (6.0g – 8.5g): Sweet spot for daily commuting and balanced performance
• Heavier (9.0g – 11g): Best for higher top speeds and lower RPM cruising on flat roads

Specifications
