Compression Spring (GY6), 1000 1500 2000 rpm contra torque spring

Compression springs do a couple of things. First, they supply the pressure to engage the belt. They also determine the rate at which the CVT transmission changes from low to high gear. A 1000rpm spring will go into a higher gear than a 2000rpm spring.

This NCY (Blue) 1000 rpm compression spring is specifically for the stock GY6, (Yellow) 1500 rpm usually for Street and (Red) 2000 rpm for Race. SOLD EACH.
