Dr Pulley Slider 18x14mm  for GY6 150cc Engine 

Dr. Pulley sliders are made of nylon which are slicker and faster than standard metal or composite material rollers found on the market.  By upgrading to sliders you will broaden your shifting range due to their special square form.  The Dr. Pulley Sliders allow the variator backplate to sit lower, is will help off the line acceleration and also pushes up higher which increase the top speed.
