Description

Upgrade your CVT performance with Dr. Pulley 25x17 Sliding Roller Weights. Unlike traditional roller weights that roll up and down the ramp of the moveable drive pulley, Dr. Pulley's patented sliding design moves linearly along the ramp — eliminating abnormal wear, preventing gear ratio deterioration, and extending transmission life. Available in 15G and 18G. Sold as a set of 8.

Sliding (not rolling) movement eliminates abnormal wear on ramp surfaces
Broadens your range of gear ratios for improved CVT tuning
Increases acceleration, re-acceleration, and top-end speed
Self-compensating design adjusts outward as wear occurs to maintain performance
Lasts longer than standard roller weights
U.S. Patent No. 7,276,004
